The program looks at the most recent research into the brains and behaviour of psychopaths and assesses the prospects for the treatment or containment of this antisocial group of people who create such a disproportionate amount of destruction. Psychopaths who have been convicted of appalling crimes explain with disturbing clarity what motivated them in their violent and destructive behaviour. They speak without shame, guilt, remorse or empathy with their victims. Though they are articulate and, at times, plausible and charming, they lack the range of emotions experienced by the rest of society. They know the difference between right and wrong but they do not feel it.
