Atheists, why do Christians believe they have to be responsible for their actions?

you ume that atheism is an excuse to not feel guilt, we still feel guilt and actually take more responsibility for ourselves because we don't automatically ume that everything is all well and good simply because we said sorry to an invisible man in the sky, the only people that feel no guilt or responsibility are usually psychopaths or sociopaths and believe it or not even some of them are christian. also as a christian are you allowed to molest children simply because your boss covers it up?
