1. Gilles de Rais
According to surviving accounts, Rais lured children, mainly young boys who were blond haired and blue eyed (as he had been as a child), to his residences, and raped, tortured and mutilated them, often ejaculating, perhaps via masturbation, over the dying victim. He and his accomplices would then set up the severed heads of the children in order to judge which was the most fair.
2. Richard Trenton Chase
Richard Trenton Chase (May 23, 1950 – December 26, 1980) was an American serial killer who killed six people in the span of a month in California. He earned the nickname The Vampire of Sacramento due to his drinking of his victims’ blood and his cannibalism. He did this as part of a delusion that he needed to prevent Nazis from turning his blood into powder via poison they had planted beneath his soap dish.
3. Jeffrey Dahmer
Dahmer murdered at least 17 men and boys between 1978 and 1991, with the majority of the murders occurring between 1989 and 1991. His murders were particularly gruesome, involving acts of forced sodomy, necrophilia, dismemberment, and cannibalism. Dahmer committed his first murder when he was 18, killing Steven Hicks, a 19 year-old hitchhiker. Dahmer invited Hicks to his house, and killed him because he “didn’t want him to leave.”
4. Albert Fish

He was put on trial for the murder of Grace Budd, and was convicted and executed.
5. Andrei Chikatilo
Andrei Chikatilo was a Ukrainian serial killer, nicknamed the Butcher of Rostov and ‘The Red Ripper.’ He was convicted of the murder of 53 women and children between 1978 and 1990. In 1978, Chikatilo moved to Shakhty, a small coal mining town near Rostov, where he committed his first documented murder. On December 22, he lured a nine-year-old girl to an old house which he bought in secret from his family and attempted to rape her. When the girl struggled, he stabbed her to death. He ejaculated in the process of knifing the child, and from then on he was only able to achieve sexual arousal and orgasm through stabbing and slashing women and children to death.

8. John George High
John George Haigh (July 24, 1909 — August 10, 1949), the “Acid Bath Murderer”, was a serial killer in England during the 1940s.

9. Javed Iqbal
Javed Iqbal Mughal (1956?-2001) was a serial killer from Lahore, Punjab, Pakistan. He claimed he killed 100 boys during an 18 month period. He had been arrested in June 1998 for sexually abusing 2 boys for money. He went off on bail, and began murdering boys shortly afterwards. Iqbal found boys on the street, charmed them into his confidence, and then drugged, raped, and strangled them. He then cut the body into pieces and put them in a vat filled with hydrochloric acid. Once all of the remains were liquified, he dumped them. He first used the sewer, until neighbors complained of an acrid stench. He then decided to use the Ravi River. The partially liquified remains of two boys, one of whom was named Ijaz, were the only ones found of Iqbal’s victims. He kept the rest in an acid drum outside his house. He also kept clothing and shoes as trophies of his crimes. When he got to his fiftieth victim, he started taking pictures of them.
