The Biological Causes For Serial Killers

Introducing a new factor that is not really known, biological reasoning could be the main reason behind someone becoming a serial killer. Even though it is reiterated throughout life and things like religion and punishment, why would someone still kill multiple times? This is because this is how they were born and wired into life. Using the use of genetic disorders, family history, neurology and other elements, it will be evaluated if the lesser-known biological reasoning is the most prominent reason.

Many serial killers did not have serial killer parents as such but what about the children of serial killers? Their genetics could be a reason why another killer was born. For example, the son of the “Rostov Ripper” Yuri Chikatilo, definitely turned out to be a criminal. The “Rostov Ripper” AKA Andrei Chikatilo murdered 52 women and children and even though his son did not do as bad, his son, in 2009, stabbed a man several times. Prior to this, he had been charged with fraud, extortion, rape, kidnapping and racketeering. Even after knowing his father and watching him get punished for this, it wasn’t a big enough deterrent and the crimes were still carried out.

Using Fallon’s research, he mentioned in his book that he had conducted scans of people in his family. When looking at a certain scan, he saw that one was like those of a psychopathic killer and to his surprise, it was his own. He is a neuroscientist with no signs of becoming a serial killer which shows that despite having this slight disability in his orbital cortex, there was no effect on him. You could argue that someone’s brain may not have always been in this certain way and only developed after killing more which explains how someone can kill again but in terms of being born with it, it would be ruled out.
