He can be tempted, of course. But the fact that he has such immense power and is able to control himself is what makes him someone to look up to. It's what makes him a hero. Villains in these stories outnumber the heroes because most people don't have the self-control to avoid using their powers selfishly.

That's why I don't think that making a "what if Superman turned evil" story is particularly interesting. Using powers for evil is the common thing.
