Usually sociopaths will look down upon us for that very reason - that we're gullible. We're weak. One person told me that he thought he was the only honest person because he would admit that he didn't have a conscience and everybody else was clearly faking it.

I was once doing a book signing and a man came up to me and said that he gave classes to people who'd been convicted of drunken driving twice. He said he felt that nearly all of those people were what I was describing as sociopathic. Which makes a great deal of sense to me. We always talk about how could you possibly, knowing that you're drunk, get behind the wheel of a car again and do that? Well, you could if you didn't give a half a damn what happened.

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.

An intelligent sociopath can learn the rules about what's good and what's bad, what people see as good and bad. But they don't get that intervening sense of guilt, that pang of conscience, on account of it. So they tend to know what's wrong or right, they just don't care. That's another thing that they can use against us: that we do care. We're predictable in that.

Conscience is the still small voice that has been trying since the infancy of our species to tell us that we are evolutionarily, emotionally, and spiritually One, and that if we seek peace and happiness, we must behave that way.

Sociopaths are not inhibited by the notion that it's wrong to be addicted, or wrong to buy illegal drugs. Also, drinking or taking drugs can be a lot of fun, and even if it's not, it can dull that painful boredom for a while. So can certain other things, like taking risks, and particularly if you take a risk-averse person and you can manipulate him or her into taking risks, that's really fun.

To learn to be charming is fairly easy - you can teach somebody to be charming and to learn human emotions - or to learn the behaviors that go with human emotions. A sociopath, a smart one, will study the way we emote, and will learn how to do that quite effectively.
