There's definitely evidence that capitalism at its most ruthless rewards psychopathic behavior. When you look at the worst corners of the American health insurance industry or the sub-prime banking market, it really feels like the more psychopathically someone behaves, the more it's rewarded.

I wondered if sometimes the difference between a psychopath in Broadmoor and a psychopath on Wall Street was the luck of being born into a stable, rich family.

Well, I had nightmares when I was doing the Klan story all the time. I had a recurring nightmare of basically being exposed as a Jew inside the Klan compound.

I'm not what you'd call a fearless type of person.

No, people back home don't realize why there is this kind of need for heroes in America at the moment. People in Britain don't really understand what's going on here. They don't understand why Camp X-ray exists.

Capitalism, perhaps at its most remorseless, is a physical manifestation of psychopathy.

I am the neurological opposite of a psychopath, in that I feel anxious almost all the time. It must be great to not constantly feel like you’ve got someone living inside your face, shooting you with a mini Taser.
