I don't think The Joker is just a made-up villain that gets beat up by Batman. I believe that The Joker is a personality, a strength, a craziness that resides in certain people. The real world is full of despair, pain, and suffering. But there are people in this world who oppose the horrors of this world, with a smile, a grin, a giggle, or even a maniacal laugh. Those are the types of people that can be called The Joker. Are they insane? Yeah, but they're probably more humane than most of us.
