The physical basis for sociopathy is approximately 50 percent inheritable, which sounds more dramatic than it probably is, because most personality characteristics that psychologists test for and study the genetics of are about 50 percent inheritable. Introversion, extroversion, it turns out that they're about 50 percent inheritable, which means that somehow sociopathy is physical, it's organic.

A conscience is, for a while anyway, pretty easy to fake.

Sociopaths are not afraid of very much, except for physical harm and dying - really primitive, basic kinds of fears. The problem with being alone for a sociopath is boredom.

We raise our children, especially girls, to ignore their spontaneious reactions-we teach them not to rock the societal boat...By the time she is thirty, the valient little girl's "Ick!"-her tendency to respond, to rock the boat, when someone's actions are really mean, may have been exciese from her behavior, and perhaps from her very mind.

One way or another, a life without conscience is a failed life.

I think con man is the usual term. When somebody comes on television to tell a lot of needy people that God will send them to heaven if they send him $200, if that's not downright sociopathic, it's close.

People ask, "What could possibly cause a normal person to torture her own child?" Well, the answer is: Nothing could cause a normal person to torture their own child. The reason that we see that happening is that there are people who don't care, who don't love - even their own children.
