Hey, I'm Jad Abumrad.

I'm Robert Krulwich.

This is Radiolab, and today we're talking about... Well, we're trying to think about what goes on in the mind of a bad person.

James Shapiro, professor of English at Columbia University.

And he said, to start, you want to know about bad?

I'll give you bad.
