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.

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."

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.

Sociopaths are not usually physically violent. A typical sociopath never kills anybody and doesn't look like Charles Manson - they look like you and me and everybody else. You're not looking for someone who's recognizably evil or scary-looking, but rather someone who looks normal. Another lynchpin is dishonesty. Lying for the sake of lying. Lying just to see whether you can trick people. And sometimes telling larger lies to get larger effects.

Someone, or some group in George W. Bush administration, took 300 million people to war against their will, based on a very giant lie. Combined with the notion of winning, that is, to me, a horrendously scary situation.

Sociopaths love power. They love winning. If you take loving kindness out of the human brain, there's not much left except the will to win.

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.
