If you see somebody really pulling for your sympathy while at the same time hurting you intermittently, you should start to wonder. If somebody plays to your pity and really tries to draw that out of you, that's not normal.

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.

I am always impressed by the fact that even the tiniest amount of being listened to, the barest suggestion of the possibility of kind treatment, can bring such an immediate rush of emotion. I think this is because we are almost never really listened to. In my work as a psychologist, I am reminded every day of how infrequently we are heard, any of us, or our actions even marginally understood. And one of the ironies of my "listening profession" is its lesson that, in many ways, each of us ultimately remains a mystery to everyone else.

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

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.

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

People ask me many times, "Aren't you afraid you're going to scare people? Aren't you afraid you're going to make people feel bad about the human race?" I look at it as entirely the opposite. Something you can understand and identify should be less frightening than something you can't. And to understand that there are people who are capable of acting without conscience, without considering other people at all, explains a lot of things.
