Many of the serial killings have been linked to mental illness, psychological reasons, and frustrations and in some cases revenge. There are many brutal serial killers from various countries with different attitudes and desires. Few serial killers have killed more than 100, while a few have murdered below 10 but violently. Since the lists of serial killers are large, we have compacted to only the 20th century sadistic killers. The main focus of serial killers in this list would be based on sadism and extreme tortures. Some of these serial killers are terrifying, scary, evil and love killing.
List of 10 most sadistic serial killers of 20th century who have tortured their victims brutally before killing:
10. Dean Corll (28+ victims)
Dean Corll was an American serial killer who along with his two young teenage accomplices abducted, raped, tortured and killed more than 28 boys from 1970 to 1973, what was called as “Houston Mass Murders”. During the 1970s, this was considered as the worst example of serial murders in the history of America. The two young accomplices of Corll named David Brooks and Elmer Wayne Henley lured or abducted many young boys to Corll’s home who were subsequently assaulted and killed by the three. The victims were usually drugged with alcohol and other drugs until they passed out. The victims were beaten when tied by rope on to a plywood-board or a bed. After torturing the victims for several days, the victims are killed by strangulation or shooting with a .22 caliber pistol. Then the sadist killer would bury them in any of the four different places – a beach on Bolivar peninsula, a beach in Jefferson County, a rented boat shed or woodland near Lake Sam Rayburn. Before the police or the law could convict him, his accomplice Henley shot Corll fatally when Corll wanted to torture, assault and kill two of Henley’s friends.
9. Robert Berdella (6+ victims)
Robert Berdella was an American serial killer who is known to have physically assaulted, tortured and murdered at least six men between 1984 and 1987. Around the age of 16, he claimed to have been sexually assaulted by a male co-worker at the restaurant where he worked. He attended the Kansas City Art Institute in 1967, during this time he engaged in animal torture at-least three times – he tortured a duck, a chicken and sedated and tranquilized a dog. He started his criminal career by drug dealing and abusing alcohol. He was arrested at the age of 19 for possessing marijuana and LSD. He is known to have had relationships with male prostitutes and was open about being gay.
Berdella started killing prostitutes from 1984, by befriending them, luring them to his basement where he repeatedly tortured and finally asphyxiating them fatally. He also engaged in killing people in different styles and involved different torture techniques such as suffocating them, injecting infected drugs, electric shocks via spatula placed across the eyelid, intoxication and enduring piano wire tied around the wrist to cause nervous damage. He is also known to have drained the blood of few of his victims after they are dead, cut them and retained few body parts with him before burying the body in the backyard. The sadist monster died of a heart attack in 1992 at Jefferson City Correctional Center.
