“Millions of Americans, especially men, have antisocial personality disorders and they don’t kill anyone,” Dr. Jack Levin, a Criminologist and Co-Director of the Brudnick Center on Violence at Northeastern University told the Daily News. “They may lie, physiologically they may cheat … but killing is just not their cup of tea.”

Who fits the profile?

According to the U.S. National Library of Medicine (NLM) and National Institutes of Health, it’s people who:

– Are able to act witty and charming

– Are good at flattery and manipulating other people’s emotions

– Break the law repeatedly

– Disregard the safety of self and others

– Have problems with substance abuse

– Lie, steal and fight often

– Don’t show guilt or remorse

– Often are angry or arrogant

But it’s the rare few who take these traits to an extreme level that particularly fascinates Levin who has spent 30 years researching criminal minds and once personally interviewed serial killer Charles Manson.

“One of the major symptoms of a sociopath is a profound skill at presentation of self,” he said. “The typical [one] looks to the world as charming, innocent, decent, as an upstanding citizen and that’s part of the secret to his success at getting away with murder and rape.
