Psychopaths: Can Genes And Brain Abnormalities Create Killers?

Are some people BORN killers? | Daily Mail Online
Understanding what motivates serial killers to murder many times over can be difficult to grasp.
Over the past few decades, scientists have begun building a clearer picture of the minds behind some of the most shocking crimes.
According to the largest forensic neuroscience library in the world, there are surprising similarities between the abnormal brains structures of mass murderers.
What's more, the differences are 'at least 50 percent caused by genetics', raising the disturbing possibility that people can be born killers.
The discovery follows research that claims there are certain genetic triggers than can create a murderer. 
One of them is a variant of cadherin 13 (CDH13), which is involved in neural connectivity, and has been linked to impulse control in extremely violent offenders.

Breakthroughs in neuroscience are changing the way criminals are defended in court. Scientific research on brain scans and DNA has provided new insight on how some kinds of criminals are different from law-abiding citizens. Differences in their brains and genes may predispose them to violence.
