A word about villains. You want to know your villains very well indeed or you’re better advised not to go inside their heads at all. A villain, by definition, is somebody different from “us.” A villain is indecent, incomprehensible, from the land of “them.” Who knows what makes them act the way they do? A decent human being can’t figure them out! And part of our ongoing fiction about ourselves is that we’re the good guys. The enduring paradox is that they think they’re the good guys.
