I can tell you are an ex-Mormon. You are still thinking like a conservative. You are thinking of a hierarchy where you are more moral than Hitler. You believe it's unfair that Hitler has a better outcome than you.
I'm asking you to think more like a liberal. Think about the actual outcome. Imagine two restaurants, one has Hitler forever one does not. If given a choice which would you choose? I'm saying that letting in Hitler indicates the quality of people in that location. Wouldn't spending eternity with people like him be hell?
