The common features of a psychopath and sociopath lie in their shared diagnosis — antisocial personality disorder. The DSM-51 defines antisocial personality as someone have 3 or more of the following traits:
Regularly breaks or flouts the law
Constantly lies and deceives others
Is impulsive and doesn’t plan ahead
Can be prone to fighting and aggressiveness
Has little regard for the safety of others
Irresponsible, can’t meet financial obligations
(I highlighted the top 3 that jump out at me.)
Possible question---Is a Trump voter just Looking for Mr. Goodbar?
(There's one crucial thing that "Looking for Mr. Goodbar" doesn't make clear: Just because you find Mr. Goodbar doesn't necessarily mean you were looking for him. The heroine of Judith Rossner's bestseller was looking. Theresa was turned on to a particular flavor of self-destructive sexual experience, one involving possible danger to herself, and she played a role in bringing about her own death.
In Richard Brooks's film version, that masochistic impulse isn't considered as openly. He gives us a Theresa who drinks too much, sleeps around too much, and takes too many drugs -- but she seems more of a hedonist than a masochist. She's looking for a combination of good times, good sex, and a father figure, for psychological reasons the movie makes all too abundantly clear. But she isn't looking for danger, mistreatment, or death. Maybe Brooks thought audiences would find Rossner's masochistic heroine too hard to understand.)
