That's what I've always liked to think, if there is someone 'up there' who judges us, it's a judgement of the person themselves, that it doesn't matter what form their belief takes.
Thing is, all of us do 'evil' everyday, we are all an unwilling or unknowing party to it in some way or another. My taxes pay for the bombs that are dropped on Houses in the Middle East, but then, I wouldn't be surprised if a fair percentage of religious donations in the Middle East find their way into the hands of those who would detonate bombs in the middle of a shopping Mall in Iraq, everyone touches 'evil' in one way or another, and I do not believe in the concept of evil done in a good cause. However, that is not going to go away, one man can change the world, several million however? No chance.
So it really boils down to trying to be the best you can for yourself.
