Playing Are Some People Genetically Predisposed to Deadly Violence?

Genes can indicate violent behaviors and Bill Sullivan shares that some people have a defective enzyme and this enzyme is deficient in clearing the neurotransmitters in the brain, leading to a toxic buildup making it easy to become aggressive and violent. He shares that some people carry the mutation and would never hurt a fly, but If you were abused as a child, your odds of getting violent go through the roof.
