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.

When I speak of divisions greater than gender or race, I say that because it is so unimaginable. I can imagine what it would be like to be another race. Or to be a man - I could draw that up in my mind and experience it. Schizophrenia? We're all schizophrenic in our dreams. Depression? Most of us have been at least a little depressed and can imagine it. But not having a conscience? Conscience is so profound and so basic in most of us.

Most of us fill up our lives and end our boredom with our involvement with other people - people we love, people we hate, people we're afraid of, people we're interested in - and that's what keeps our minds going. So if you're sociopathic and you really have no caring for anybody, there's not much left, only boredom, and the way to relieve that, apparently, is to play a game and make sure that you win.

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.

Controlling others—winning—is more compelling than anything (or anyone) else.

I would hesitate to tell people to stop being kind or sympathetic to sociopath. But just like loyalty, some things that can be taken advantage of are empathy, sympathy, and our tendency to pity somebody when something has gone wrong in their life.

Sociopaths are not usually physically violent. A typical sociopath never kills anybody and doesn't look like Charles Manson - they look like you and me and everybody else. You're not looking for someone who's recognizably evil or scary-looking, but rather someone who looks normal. Another lynchpin is dishonesty. Lying for the sake of lying. Lying just to see whether you can trick people. And sometimes telling larger lies to get larger effects.
