The female psychopath I know and mentioned is neither young nor pretty. Still she is legally held accountable for none of the harm she does or the lies she gets caught telling on the witness stand. Psychopaths are somehow blessed or charmed people. Don’t know why.
Have you ever read “The Sociopath Next Door”? It’s about sociopaths in every day life. Most of them are not in jail. It’s written by a doctor, but not a dry read at all. It’s incredibly interesting. One of the main things sociopaths do is play on people’s sympathy and pity. In general if you feel sorry for someone, you are willing to give them a pass and forgive a lot of things.
Well, I think that psychopaths and sociopaths are all experienced in charming their victims. It is a skill that they practice all their lives. They often are called “charismatic”. They don’t have to be pretty, but the pretty ones have a better chance of success.
