Re: The ultimate goal of Man Of Steel and what it means to be Superman.
I don't believe power necessarily corrupts. I think it reveals.
It amounts to one's virtues and the honesty and courage of those virtues. I agree that Superman is exceptional in how he uses his powers.
I'm a huge fan of Nietzsche's philosophy, who's terribly misunderstood. Nietzsche believed that it was a virtue for the powerful to be generous. Not out of charity but philanthropy because one is overflowing with ability. In a sense, greatness is demonstrated in how much you can give.
That's what Dr. Manhattan reveals. He can do anything but ultimately abandons humanity. Superman dedicates his life to inspire excellence and help out because he genuinely values humans instead of looking down on them.
