It amuses me how you can’t imagine that an atheist could be a moral being. It’s one low blow after another from you! An atheist may not believe in the hereafter, but he/she will believe in the consequences of his/her actions and the law of the land. That should be enough to prevent him/her from committing a crime. If they still choose to do so, they have already decided to go against the law and give up their morals. Same goes for a religious person, the moment they decide to committ a crime, they give up their right to claim to be moral.
