"Because Batman is fully human and because a horrible trauma leads him to wear a mask and wage his war on crime, we can contemplate real psychological issues that drive people to do extreme things. Psychologists can examine how well he does or does not fit the symptoms of a variety of disorders. Nobody thinks it's weird for Superman to apply his natural gifts to help the members of this human race in a manner that keeps him above it all. When a guy runs around dressed like a bat, we have to wonder: Why the mask, the bat, and the underage partner? Why does he really wear a costume to fight crime? Why are his most intimate relationships with "bad girls" he ought to lock up? And why won't he kill that homicidal clown?"
