Batman - mortal, flawed, tormented
I agree with the supporters of Batman, for mostly the same reasons. As I almost posted in the 'favorite character' thread, I'm a dedicated fan of the reluctant hero, which batman is imo. Superman is a hero because of his powers; he can, so he does. Batman is a hero because of the slaying of his parents - which you may say is voluntary, but I think it's a psychological compulsion for him. Batman would prefer to be normal, live a normal life, and let the police handle the criminals, but since his family was taken from him he can no longer have a normal life. He has several major character flaws as a human being, but he makes up for it by fighting evil. Superman is just too perfect - very unrealistic.
