First look at Jared Harris as Professor Moriarty in Sherlock Holmes: A Game Of Shadows.
"I think that for me—and this is again my rational, it’s never explained in the story and I don’t really think it needs to be—but for me, the character’s amoral. He’s moved beyond the concept of there being a heaven and a hell and a God and a devil, and there being good and evil, he doesn’t believe in it. And if you don’t’ believe in that moral construct, then everyone is free to do whatever they want. He sees that whole approach to viewing the world and everything around them as being a childish construct. He doesn’t believe in the whole idea of there being good and evil, so he couldn’t conceive himself as being either good or evil. He’s just doing what’s good for him. It’s like asking, if you’re a fish, how could a fish conceive of space? You swim in the water that you swim in or the atmosphere that you’re in. For him it just doesn’t exist. The whole idea doesn’t exist."
