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.

If you don't have a conscience, what is your behavior like? Apparently, if you don't have a conscience, if you don't really . . . love, then the only thing that's left for you is the game - it's about controlling things.

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

I am not allowed by my profession to diagnose somebody from a distance, but one can observe certain symptoms of sociopathy in George W. Bush.

The ultimate manipulation is to kill someone, and sociopathy is murderous in a psychological sense - there's a kind of soul-murder going on.

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.

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.
