Hi
My MIL is an athetist and I've had atheist friends in the past. They are the most morally corrupt people I've ever met.
People who believe in God or some form of higher being and an ultimate judgement day or reward (even through reincarnation) live by a certain set of rules e.g. 10 commandments. In a way it makes you aware of a higher being or that you will eventually be held accountible for your actions and should (in an ideal world) stop you doing bad things.
People like my MIL sleep around and do whatever they please regardless of who they hurt or how immoral the act is. As long as she's not breaking any laws of the land (and adultery is not one of them) she thinks it's fine to get away with it. Because she doesn't believe in God, she believes that she has in fact "got away with it".
What are your opinions on this? How do atheists enusre they don't do bad things? Whih set of rules/principles do you follow?
