00:00H.H. Holmes ran a fully integrated system of murder, corpse preparation, and body sales.
00:06Welcome to WatchMojo, and today we're exploring our picks for the most dangerous,
00:10violent, and remorseless criminals in history who've been diagnosed by professionals
00:14or have displayed traits of psychopathy in their lives.
00:17You always had that glint in his eye that you kind of figured there was something there that was wrong.
00:25David Berkowitz, a.k.a. The Son of Sam.
00:28Berkowitz reveals details about a deadly cult that he says claimed his soul.
00:34There was a force of evil that was just so, so powerful, just so powerful,
00:40it's beyond any human comprehension or understanding.
00:42Even as a child, the signs of psychopathy were there for Berkowitz,
00:46who would become known as the Son of Sam.
00:48As well as threatening behavior, he was known to start fires.
00:51In 1976, Berkowitz began targeting random people in New York City and taking their lives.
00:56By 1977, he had killed six people.
00:59By chance, a survivor saw Berkowitz's car get a parking ticket, leading to his arrest.
01:04During questioning, Berkowitz claimed he was told to kill by a demon possessing his neighbor's dog,
01:09hence his moniker.
01:13However, he later admitted this was a hoax.
01:18In 1978, after being declared competent to stand trial, Berkowitz pleaded guilty to his murders
01:23and received six consecutive life sentences.
01:26You know, as a Freudian psychologist, he had these certain moles you have to go into.
01:30It always reverts back to the childhood, the mother, a bad relationship.
01:34But that was completely false.
01:37Marcel Pettio.
01:37With no other witnesses to tie him to the murder, Pettio once again avoids arrest.
01:43It takes a psychopath to take advantage of victimized people.
01:46And that was certainly the case with Pettio during World War II.
01:49When Germany occupied France, Pettio set up an underground network to help Jewish people
01:53escape persecution for a fee.
01:55At least, that's what he advertised.
01:57In reality, Pettio lured them to his home and gave them a
02:00vaccination that was actually a fatal poison.
02:02In 1944, after neighbors had alerted the authorities due to a foul smell coming from Pettio's home,
02:08his crimes were discovered as they found human remains and a lot of luggage.
02:12While he was convicted of 26 murders, it's believed the number could be over 60.
02:17In 1946, Pettio was executed.
02:19It is quite rare to see somebody who's quite so articulate,
02:23quite so, you know, professionally capable as Pettio is.
02:27And to have somebody like that, who's also got the psychopathic features,
02:30to be very charming, very glib, up to a point,
02:33it ceases to become a bad whether he's found guilty or not.
02:36Leonard Lake.
02:37Despite these attempts to live out his fantasies,
02:40Lake, like many serial killers, had been aware of the ultimate hopelessness of his position.
02:45The thrill of capturing and killing his victims soon wore off.
02:49Many psychopaths enjoy abusing animals as children.
02:52That was the case with Lake, who, when young, used chemicals to dispose of mice.
02:56In 1985, he was arrested for shoplifting.
02:59During questioning, he took his own life.
03:01The investigation led the police to a cabin in Wilseyville, California,
03:05where human remains, a dungeon, journals of the crimes,
03:08and videotapes of abuse to victims were found.
03:11Forensic specialists dusted for fingerprints and latent evidence.
03:15They hoped that if Lake had indeed kept a prisoner here,
03:18he or she had left behind some clue of their presence.
03:21For several years, Lake and accomplice Charles Ng had been abducting,
03:25abusing, and murdering people at the remote cabin.
03:27In 1999, Ng was convicted of 11 murders and sentenced to death.
03:32While the cabin seemingly had human remains belonging to 11 people,
03:35it's speculated, due to Lake's journals, that there could be 25 victims.
03:39She doesn't need a doctor, I'm a doctor.
03:43You don't need a doctor, do you?
03:45Huh?
03:49John Cribb.
03:50According to forensic psychologist Tim Watson-Monroe,
03:52Cribb is a, quote, end-of-the-line psychopath,
03:55and the closest he's come to, quote, evil simpliciter.
03:58In 1978, Cribb broke into a house in the Balcombe Hill suburb of Sydney, Australia,
04:03taking Val de Connell and two of her children hostage.
04:06He doesn't stop at the drop-off point,
04:08and continues on further,
04:10taking the car to an isolated bush clearing near Ellenborough Falls.
04:14After assaulting Connell, he left the trio in the wilderness,
04:18only to change his mind and take their lives.
04:20After crashing his car, the bodies were found in the trunk.
04:23Cribb was sent to a psychiatric hospital, but he escaped.
04:26After armed robberies, he then assaulted teenagers before being arrested.
04:30In jail, he sent Christmas cards to taunt his victims.
04:32In 1979, Cribb was sentenced to three consecutive life sentences,
04:37plus 42 years before dying in 2018.
04:40Bela Kis
04:41In 1916, a landlord wanted to renovate the property
04:44that Kis was renting in Sincota, Hungary.
04:47However, he had been conscripted into the army two years before.
04:50When the workers went to Kis' workshop to search for materials,
04:53they instead found several tin drums.
04:56When they opened them, they discovered bodies submerged in alcohol.
04:59During the search of the property, 24 bodies were found,
05:02and letters from Kis to many more women, too.
05:04Seemingly, he had been defrauding them with the promise of love,
05:07only to take their money and lives.
05:09When the authorities heard Kis was at a Serbian hospital,
05:12they rushed there.
05:13However, he had already escaped.
05:15While there have been sightings worldwide, Kis was never caught.
05:18John Wayne Gacy, a.k.a. The Killer Clown
05:21No one had ever had to handle anything like this before.
05:26And at the time, I didn't know what the totality of this thing was going to be.
05:32After being arrested in 1968 for assaulting a teenager,
05:35Gacy was diagnosed with antisocial personality disorder,
05:38which is closely tied to psychopathy.
05:40Despite this, he was eventually released after serving 18 months of a 10-year sentence.
05:45By 1972, Gacy began taking lives.
05:49Oh, I heard a weird sound.
05:53Just a sump pump pumping out the gun.
05:56No, not that.
05:57It's a strange whining noise.
06:00Maggots.
06:01He lured men and boys to his property in Norwood Park Township in Chicago, Illinois.
06:05Gacy would then restrain them, often pretending to do a magic trick since he moonlighted as a clown,
06:10before killing them.
06:11The disappearance of Robert Piest in 1978 led the police to Gacy,
06:15where they discovered human remains hidden in his home's crawlspace.
06:19In 1980, Gacy was found guilty of 33 murders and was sentenced to death,
06:23which was enacted in 1994.
06:25You were there, right?
06:27Not during the crime, but I was there afterwards, and I watched the removal of the body.
06:32And what happened to the body afterwards?
06:34It was one that was...
06:35That body was put into the river.
06:37It was taken to the river and dumped in the river.
06:38Pedro Lopez, a.k.a. the monster of the Andes.
06:42Lopez was very good at using his words to manipulate others.
06:47People with personality disorders are very smart,
06:50and they use their language in a way to try to justify their actions very well.
06:54Known as the monster of the Andes,
06:56Lopez prayed across multiple countries in South America.
06:59In 1980, he was arrested in Ecuador for attempting to abduct a girl,
07:02while in jail.
07:03Alongside him was an officer posing as a prisoner.
07:06Lopez proudly proclaimed to his cellmate the many, many lives he had taken.
07:10In 1980, he received the maximum sentence of 16 years for taking 110 lives,
07:16but it's speculated it could be over 300.
07:24Upon his release in 1994, Lopez described himself as the, quote,
07:29man of the century.
07:30When he was deported to Colombia,
07:32the cops were unable to charge him with anything but sent him to a psychiatric hospital.
07:36After his release, Lopez vanished in 1999 and hasn't been seen since.
07:41He went back into the countryside he knew so well,
07:44to the killing ground where he had found so many victims.
07:50That was the last time anyone reported seeing Pedro Alonso Lopez.
07:55Alday Hussein.
07:56Uday did not believe it was sanitary to have his dogs retrieve the birds he'd shot.
08:01So he would force friends like this man to go fetch in the icy water.
08:05His father, Saddam, was sadistic, but Alday is far worse.
08:09Egypt's former president Hosni Mubarak even called him a, quote,
08:13psychopath after he killed Kamil Hanajago at Mubarak's wife's birthday party in 1988.
08:18Alday was appointed by his father as chairman of the Iraqi Olympic Committee
08:21and the Iraq Football Association.
08:23Rather than stick to boardrooms,
08:25he would abduct what he felt were underperforming athletes,
08:28take them to his private prison, and then abuse them.
08:30Alday was also tied to several more murders
08:32and was alleged to assault women and girls, sometimes fatally.
08:36In 2002, during the Iraq War, U.S. soldiers killed Alday and his brother, Kosai.
08:40He is also rumored to use heroin regularly.
08:44But all of this does little to stem his feelings of paranoia.
08:48Jeffrey Dahmer, a.k.a. the Milwaukee Monster.
08:52Come on.
08:52I'm not going in there.
08:53Stop!
08:54You're like...
08:55I got neighbors.
09:00In 1991, when police officers in Milwaukee, Wisconsin were flagged down by a frantic and
09:05half-handcuffed Tracy Edwards, they had no idea what they were in for.
09:09Edwards took them back to the apartment he had escaped, where they found Dahmer.
09:12During the investigation, the cops uncovered photos of bodies taken inside the property
09:16and human remains in the fridge and within a large drum.
09:19I was dead set on going with this compulsion.
09:24It was the only thing that gave me any satisfaction.
09:31Diagnosed with several personality disorders,
09:33Dahmer confessed to taking 16 lives and consuming some.
09:36Over the space of two trials in 1992,
09:39Dahmer, with 17 victims, was sentenced to 16 counts of murder, earning him life imprisonment.
09:45In 1994, he was killed by fellow inmate Christopher Scarver.
09:49You know, I'm just glad the monster's gone.
09:52And that's the bottom line.
09:53Adolf Hitler.
10:03After rising to power in 1933,
10:10Hitler transformed Germany into a cruel machine to wipe out anyone who wasn't Aryan.
10:14As well as provoking World War II in 1939,
10:17he instigated mass genocide through his parliamentary forces and with extinction camps.
10:22The latter took the lives of around 6 million Jewish people across Europe
10:25and millions more with backgrounds Hitler disliked.
10:28It's estimated that up to 85 million perished from the war,
10:40making it the most out of any human conflict.
10:42When he realized he was set to lose,
10:44Hitler took his own life in 1945.
10:47While he wasn't formally diagnosed with any mental illness,
10:50researchers have theorized he was a psychopath
10:52due to sharing several traits linked to the condition.
10:55We must understand the leaders we're contending with.
11:00You can't deter, optimally, a leader you don't understand.
11:04Richard Ramirez, a.k.a. the Night Stalker.
11:08Richard Ramirez brought terror to California in the 1980s.
11:11His M.O. was home invasion, followed by heinous crimes.
11:15The dreadful and indiscriminate crimes caused a wave of fear.
11:21Everybody was scared.
11:23Everybody in the county of Los Angeles and Southern California was scared to death.
11:31He boasted about 15 victims, yet there are probably more.
11:34Ramirez came from a troubled childhood,
11:36as his father was a violent man with alcohol use disorder.
11:40This likely contributed to his psyche,
11:42as did physical brain trauma from the events.
11:4525-year-old Ramirez had begun worshipping Satan in his late teens
11:50and would often leave pentagrams at the scene of his crimes.
11:54As well, his cousin Mike was a wartime Green Beret
11:57and would sometimes share gruesome photographs with Richard,
12:00who claimed he was fascinated rather than offended by the images.
12:03In addition to a traumatic childhood,
12:05Ramirez showed impulsiveness, criminal versatility, and lack of remorse,
12:10all traits on the hair psychopathy checklist.
12:12Such is his reputation that extra security was set up outside the courtroom,
12:17and many spectators crowded around for a glimpse of an accused serial killer.
12:21Albert Fish, a.k.a. The Gray Man.
12:24Fish could have easily passed for someone's grandfather,
12:27but this was not your average grandfather.
12:30Albert Fish was born in 1870,
12:32and was once placed into an orphanage for about five years.
12:36In the orphanage, he suffered harsh physical punishments,
12:38at which point, Fish noticed that such violence caused him pleasure.
12:42Fish is regarded by many aficionados of crime as the scariest
12:46and most deranged of all American serial killers.
12:50Partly, I think it was because he was so, he seemed so benign.
12:54He found himself fascinated with mutilation
12:56after seeing anatomical bisections at a museum.
12:59Fish would also attack himself,
13:01displaying the tendencies often seen in psychopaths.
13:04Fish would capture young people,
13:06and claimed numerous victims.
13:08On the psychopath checklist,
13:10Fish would tick off lack of empathy and remorse,
13:12as well as impulsivity, among many others.
13:15Those psychiatrists who testified for the prosecution that he was saying
13:19were correct,
13:20and I think that they were able to support their findings
13:24with Fish's own behavior
13:27that shows pre-planning, clarity of thinking,
13:30and a real awareness that this was something that was illegal and wrong.
13:37Albert DeSalvo, a.k.a. the Boston Strangler.
13:40Albert DeSalvo took the lives of over a dozen women between 1962 and 1964,
13:46in most cases by entering their apartments.
13:49As the number of victims grew,
13:50police became more and more frustrated.
13:53No woman felt safe.
13:55DeSalvo was initially convicted in late 1964
13:57for a series of crimes dubbed the Green Man Attacks.
14:01He invented a routine to con gullible young women,
14:04relying heavily on his ability to charm.
14:06In custody, he confessed to many crimes.
14:09Much like others on this list,
14:11DeSalvo grew up in a problematic home.
14:13His father tormented his wife in front of their children.
14:17DeSalvo began to mistreat animals at age 12.
14:20Forensic psychologist Jay Reed Malloy points out
14:23that psychopaths tend to devalue their victims.
14:26DeSalvo would put neckties on his victims
14:28and position their bodies in horrible ways,
14:30a form of posthumous devaluation
14:32in turning them into displayed objects.
14:35He wanted to be world-renowned.
14:37And, of course, if you confess
14:39to the worst serial murder since Jack the Ripper,
14:42you're going to be famous, infamous.
14:44Dennis Rader, a.k.a. the BTK Killer.
14:48Dennis Rader was convicted of 10 killings
14:50that took place between 1974 and 1991.
14:54Rader, like numerous others on this list,
14:56also displayed typically brutal animal mistreatment
14:59in his youth, capturing and killing them.
15:02His main motivation was realizing his twisted fantasies,
15:05hence the nickname he gave himself, BTK.
15:08In my mind, there was two people in that body.
15:11One of them was a husband and father,
15:14the Boy Scout leader.
15:15The other one was an absolute animal.
15:17He is an unconventional psychopath to some experts,
15:21as one of the key traits is lack of acknowledging
15:23responsibility for one's actions.
15:25Rader sent taunting letters to media outlets
15:28and law enforcement, boasting about his crimes.
15:31BTK began today's letter with a question.
15:33How many do I have to kill before I get a name in the paper
15:36or some national attention?
15:38Though he ticks the grandiose sense of self-worth box,
15:42boasting about responsibility separates him
15:44from some textbook psychopaths.
15:45He remains in solitary confinement,
15:48where he will stay for the rest of his life.
15:51Elizabeth Bathory, aka the Blood Countess.
15:55Though her guilt is actually still debated by historians,
15:59Hungarian Elizabeth Bathory was a countess
16:01who lived between 1560 and 1614
16:04and allegedly took the lives of around 600 young women.
16:08Elizabeth Bathory had a terrible temper
16:09and she enjoyed torturing people.
16:13She enjoyed humiliating them.
16:14Many of her victims were sent to her by their families
16:17in order to learn proper etiquette,
16:19a typical practice at the time.
16:21She is said to have bathed in blood
16:23in order to maintain her youthful appearance,
16:25but this is also highly debatable.
16:27Her sadistic reputation was beginning to strike fear
16:31into the hearts of all who heard her name.
16:34You must imagine these people cowering outside the walls of her castle,
16:38never knowing what exactly is going on in there,
16:40but knowing at the same time that they are absolutely subject
16:43to this person's power, to this person's whim.
16:46Bathory reportedly displayed mental health issues from the age of five
16:50and was exposed to executions and the beatings of servants from a young age.
16:54She also displayed obvious disturbed public behaviors in her adult life,
16:59watching others suffer for pleasure or harming them herself.
17:02She was allowed to live.
17:03She was imprisoned in her castle.
17:06That's what we've been led to believe
17:07and that no one was allowed to talk about her or say her name for 100 years
17:11meant that they almost just wrote it out of history.
17:14Vlad the Impaler, a.k.a. Vlad III, a.k.a. Vlad Dracula.
17:19The story goes that Romania's bottomless well of tyranny,
17:22catastrophe and overall human misery
17:24can all be traced back to one terrifying ruler
17:27and his supernatural evil.
17:29Vlad III was born somewhere between 1428 and 1431,
17:34second son to eventual leader of Wallachia Vlad Dracul.
17:38Recognize that?
17:39What's the connection between the historical story of Vlad the Impaler
17:42and the story that Bram Stoker gave us of Count Dracula?
17:46He's decided to write a book about vampires,
17:50so he picked up a guidebook on Transylvania
17:52and he found this name, Dracula,
17:55and it just sounded so evocative.
17:57Dracul was a member of the Order of the Dragon,
18:00a society that opposed the Ottoman conquest of Europe.
18:03As a result of this,
18:04little Vlad and his brother Radu were taken hostage
18:06by Ottoman Sultan Murad II
18:08in an attempt to gain Dracul's loyalty.
18:11After this ordeal,
18:12Vlad's father and older brother were killed.
18:14When in power,
18:16Vlad had a particular penchant for impaling his enemies
18:19and leaving them to die.
18:20To this day,
18:22he's still referred to as Vlad Tepes,
18:25Vlad the Impaler,
18:27in memory of his favorite method of killing.
18:30He was responsible for an estimated 80,000 deaths.
18:34Some psychological researchers claimed
18:35Vlad fit the dark triad mold,
18:38which consists of Machiavellianism,
18:40narcissism, and psychopathy.
18:42With Vlad,
18:43we have a man who didn't care how much blood he spilt.
18:46Finally, we have the name Dracula.
18:49Today, it has a deadly sound to it.
18:52It means son of the devil.
18:54The devil, of course,
18:56a horrific, vengeful,
18:59impossible-to-stop creature.
19:02And that is exactly the image that we have
19:04from the real Vlad Dracula.
19:06H.H. Holmes
19:08Dr. Herman Webster Mudgett,
19:10better known as H.H. Holmes,
19:12was a career criminal guilty of a number of crimes,
19:15including forgery,
19:16illegal marriage,
19:17and causing deaths.
19:18He was apparently very handsome
19:20and had an incredible personality,
19:24and women were drawn to him in large numbers.
19:27He is best known as the proprietor of the murder castle,
19:30which was subject to so many sensationalized stories
19:33that it's impossible to give an actual account
19:35of its layout or events.
19:37Holmes' childhood was harsh,
19:39as is the case with most of the others on this list.
19:42The middle child of a stern postmaster
19:44and devoutly religious mother,
19:46he grew up a mummy's boy.
19:48He took to science
19:49and found confidence designing scarecrows
19:52and perpetual motion machines.
19:54His father had alcohol use disorder,
19:56and he was treated badly by his schoolmates
19:58due to his academic proficiencies.
20:00Holmes became obsessed with anatomy and dissection,
20:03performing the latter on animals.
20:05He was convicted of causing only one death,
20:07but is presumed to have committed four more
20:10and is suspected of nine.
20:12You are cleansed and delivered.
20:15May God have mercy on your soul.
20:19As Holmes waits for his life to come to an end,
20:22he remains cool and composed.
20:24Ed Gein, a.k.a. the Butcher of Plainfield.
20:28Ed Gein was a killer and body snatcher,
20:30exhuming and stealing human remains from cemeteries.
20:34Gein was born to a militantly religious mother, Augusta.
20:37Augusta would forbid her children from making friends,
20:40contributing to Ed's poor social skills.
20:42The family farm went to Edward
20:44upon the deaths of his family members.
20:46He reportedly boarded up all rooms used by his mother,
20:50leaving them spotless compared to the rooms
20:52in which he lived.
20:52The house became unimaginably filthy,
20:55with layer upon layer of waste, slop,
20:58and unidentifiable clutter.
21:00Gein was eventually discovered to have fashioned
21:02a long list of objects from human body parts.
21:05For example, skull bowls and a skin lampshade.
21:08They found all types of things that belonged to people
21:12that were no longer people.
21:14Gein was diagnosed with schizophrenia and also psychopathy.
21:17There's no way in the world that anyone could ever decipher completely
21:21or even intelligently what Ed was thinking or doing.
21:28Charles Manson.
21:28Tell me in a sentence who you are.
21:38Nobody.
21:39Charles Manson was understandably evaluated a number of times while imprisoned,
21:43resulting in various diagnoses such as schizophrenia and personality disorders.
21:48After Manson's death,
21:50his initial evaluations by psychologist Todd Roy were publicly released,
21:54giving other professionals the chance to weigh in.
21:56What we learned from Manson is how somebody can be affected
22:00to a point of having psychiatric problems
22:03and still be charismatic and manipulative enough
22:07and have enough going on upstairs to plan and organize two massacres.
22:15More modern researchers claimed Manson was more on the bipolar spectrum,
22:19displaying psychopathic, narcissistic, and antisocial behaviors.
22:23Are you mad?

22:25Manson attracted followers easily,
22:35a sign of grandiose self-worth as seen on the hair checklist.
22:39His Rorschach test answers were apparently consistent
22:42with under 1% of comparable results.
22:45He also came from a troubled childhood with a neglectful mother,
22:48unstable father figures,
22:49and time spent in a boys' school where he was beaten for the smallest infractions.
22:54There was no reason to say that Charlie's early life as a child was ideal.
22:59Having your mother in prison never is.

23:17Ted Bundy
23:18He was sharp.
23:19You couldn't put anything over on him.
23:22He liked to play games where he'd make us look like fools,
23:25like he was dealing with inferiors.
23:27Just simple, low-life, country bunk and deputies.
23:31The infamous Ted Bundy confessed to dozens of horrific crimes between 1974 and 1978.
23:37Bundy confessed to all eight Seattle killings
23:39and 15 more in Oregon, Utah, and Colorado.
23:42He gave police information on dozens of other unsolved cases.
23:46Though recollections of his childhood are scattered,
23:48with differing stories from different people, including Bundy himself,
23:52it is seemingly the case that he never had a clear father figure.
23:56He was made to believe his grandparents were his actual parents
23:59and his mother, his sister.
24:01From an early age, Ted sensed he was living a lie.
24:04The truth clearly marked him in some way.
24:07Bundy was initially diagnosed a psychopath by prominent psychiatrist Hervey Cleckley in the late
24:121970s, yet has subsequently also received many other psychiatric diagnoses and designations.
24:18Bundy had a successful mask of sanity.
24:21He could easily charm his victims into trusting him.
24:23He graduated in June of 1972 from the University of Washington with a degree in psychology.
24:30Why does he get a degree in psychology?
24:31From my view, he does that because he wants to be able to continue to manipulate people.
24:36What other horrible psychopaths did we miss from this video?
24:40Let us know below.
24:41They call Bundy a master manipulator, and they vow that despite all his talking,
24:47the state will strike no deal to delay Bundy's execution.
24:50That's good.
24:51That makes it Sophie lapsed the legend.
25:02Don't go north.
25:04He might be passed away so that it should go around it.
25:07If he missed sociedade she can only givecrackules better than the end of his conversation and
25:11Tony made the secret of mine.
25:14Tell that the aggressive syndrome will react to his first section.
25:17Don't go all around.
