Serial killers and true crime

A video documentary that looks at psychopaths. Not all are serial killers.
1 in every 100 person is a psychopath by some studies. (Other studies vary by only small amounts.)
All serial killers are psychopaths though.
Smart, charming, usually decent looking.
Conceited, arrogant, callous, egocentric and grandiose. (Though they hide all this pretty well.)
Usually other people are almost drawn to them, they like them, they trust them.
They are not mentally ill.
They were not abused.
They do not have brain damage.
They do not process emotional information the way everyone else does.
There is a lack of fear, a lack of inhibition.
They are cold blooded and fearless, blind to the emotions to others.

This documentary has some suggestions, ideas, insights.
There may be something different in their ‘wiring’. ?
Not answers, not cures, but maybe something like understanding. ?
Even brain scans can give hints, but as the doctor CLEARLY shows, not absolutes.

Ted Bundy, Jim Jones, Ian Bradley, Dennis Rader (BTK) are looked at.
