The reason I want to explain that you're probably never going to get revenge a sociopath and you're also probably not going to redeem this person, is that it is not a project that will ever succeed. At present, if a person does not have a conscience, we know of no way to instill one - not even a little bit. It's not like something you can take off the shelf and put into somebody's brain. It makes me so sad to hear people say, "I think I can see just a little bit of a conscience."

Most of who we are is our deepest emotions, and someone who cannot feel those emotions in a positive way is never going to understand much about his fellow human beings.

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.

We are all a little crazy.

Even famous people - are most concerned of all with what people who are close to them think. And the sociopath is generally not concerned with that at all.

I think con man is the usual term. When somebody comes on television to tell a lot of needy people that God will send them to heaven if they send him $200, if that's not downright sociopathic, it's close.

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.
