You can't have a Superman that is battling cultural morality. You need a Superman that has built in sort of values.

We can deny angels exist, convince ourselves they can't be real. But they show up anyway, at strange places and at strange times. They can speak through any character we can imagine. They'll shout through demons if they have to. Daring us, challenging us to fight.

The thing about 'Dark Knight' is its objective is to set Batman into your world, so that you can imagine the moral dilemmas he faces are exactly parallel to moral dilemmas that you would face in this world, today, if you were out there fighting crime dressed like a bat.
