"I know that Superman could squash me like a bug. But I know he won't. Because deep down, Clark is a good person. And deep down, I'm not." - Batman.

Superman has a strong moral compass and Batman has a battered one. To be honest, if Superman wanted it, he could kill Batman but he won't and Batman is known for his preparation for any situation so he would defeat Superman.
