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."

If you don't have a conscience, what is your behavior like? Apparently, if you don't have a conscience, if you don't really . . . love, then the only thing that's left for you is the game - it's about controlling things.

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.

Conscience is a creator of meaning. As a sense of constraint rooted in our emotional ties to one another, it prevents life from devolving into nothing but a long and essentially boring game of attempted dominance over our fellow human beings, and for every limitation conscience imposes on us, it gives us a moment of connectedness with an other, a bridge to someone or something outside of our often meaningless schemes.

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.

The physical basis for sociopathy is approximately 50 percent inheritable, which sounds more dramatic than it probably is, because most personality characteristics that psychologists test for and study the genetics of are about 50 percent inheritable. Introversion, extroversion, it turns out that they're about 50 percent inheritable, which means that somehow sociopathy is physical, it's organic.
