Is It a Family Trade?

Could serial killing just be in family blood?

If a parent was a serial killer, it would make sense that their child would be exposed to elements of the nature, and might pick up on their habits that could eventually lead them towards a future in killing. However, a Minnesota twin study shows that psychopathy is 60% heritable, so psychotic traits are due more to DNA than their upbringing.

A correlation has been discovered between criminal psychopathy and brain abnormality, which can also be passed down through a family.

If a child had a parent that was a serial killer, it would most likely be a disturbing life. They might have to suffer from the torturous fantasies of their parent(s) and could even be forced into involvement in crimes, or be killed. It would more than likely be a very hard life to live. While children are young, many wish to follow in their parents' footsteps. These children just might be dangerous if they wish to follow theirs.
