WHY PEOPLE BECOME ATHEISTS?

I think it's different for different people, but I think that some people are driven away from God and become unbelievers because of some of the things that they are taught to believe about God, and because some people either use God as a weapon or use God to try to explain and make sense of all the bad stuff that happens. I keep hearing things like, "It was the hand of God," or "It was all part of God's plan," when someone does something to hurt someone. I guess they think that this is somehow supposed to help people be at peace with whatever happens to them, at the hands of evil people, but it doesn't do that for me. It just makes me angry. I can understand why some people, when they hear these things, want to run as far away from God as possible, or just stop believing. But then I have to remember that these people don't know any better than I do why bad things are allowed to happen, they just want to believe that they do.
