The most evil and notorious serial killers in history. Andrei Chikatilo, Rodney Alcala, Ted Bundy, BTK and Harold Shipman. Who is not fascinated by the serial killers? For the most part, serial killers commit murders purely for psychological satisfaction in order to satisfy their own selfish needs.
Serial killers here are as defined by FBI: someone who commits two or more murders with "cooling-off" periods. The cooling-off period marks the difference between a spree murder and a serial murder.
There is no generic template or a single factor that leads to the development of a serial killer rather a multitude of factors such as other violent offenses, biological, social, and psychological traits. Each killer is driven by their own unique motives or reasons and is not limited to a specific demographic group, such as their sex, age or race.
“What I did was not for sexual pleasure. Rather it brought me some peace of mind.”
– Cannibal Andrei Chikatilo, who ate the organs of his victims.
