What might help would-be psychopaths

We need to talk about Kevin. Kevin Khatchadourian is a 15-year-old boy who committed a massacre at his high school and killed his father and sister. Growing up, he exhibited early signs of psychopathy: chronic unrest during infancy, failure to bond with others, animal torture and sibling abuse. He was also precociously intelligent and displayed no emotion – other incipient hallmarks of the disorder.
