There is no god there is only people, their fear of death and their need to justify their actions. They justify poor behavior by calling it sin so they can forgive themselves by asking an imaginary friend for forgiveness. It's easy to feel good about yourself if you're an awful person as long as you're a Christian. As an atheist I see "sin" as being a dick. I try not to be a dick and when u do something I feel bad for I actually learn something instead of just saying sorry and getting over it. The world is full of people who behave poorly. You call it sin because you're stupid.
