See, if I were to write him, I'd do it in a Miracleman sort of way. He knows that he's better than everyone and can run the planet, but he won't. He'll try to improve things for people but they'll always fall to pieces because of the human condition and human free will. Every time someone tries, it never works, like in Kingdom Come or For Tomorrow (Azzarello had the right idea just the wrong execution of it). Most people don't want to see that though, which is why I really don't like the character. There is potential, but no desire.
That's why I like Marvel characters more. They focus on the superpowered individual and the internal struggle more than the superheroics and the idealistic world they live in.
