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.

Sociopaths are often extremely charming. They are people who are better than you and me at charming people, at being charismatic. I've heard this more often than I can count: "He was the most charming man I ever met," or, "She was the sexiest woman I ever met," or, "The most interesting person I ever met . . ."

Some parts of the population are starting to realize that character is extremely important and that it cannot be measured by the things we like to measure it by: the tabloids and so forth. Character is crucially important to a leader, to be a moral leader, and we'd better make it primary on our list or we're going to keep getting more of the same.

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.

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

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.
