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.

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.

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.

The perfect victim, from the sociopath's point of view, is the person who is smart enough and capable enough to do him some good in the world and who is also fun to manipulate. How much fun is it to manipulate someone who is stupid and incompetent?

The most reliable sign, the most universal behavior of unscrupulous people is not directed, as one might imagine, at our fearfulness. It is, perversely, an appeal to our sympathy.

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.

I saw a werewolf drinking a pina colada at Trader Vic's. His hair was perfect.
