Aren't you rejecting the idea of a personal philosophy that provides a moral standard? An atheist may not believe that he'll go to hell for his actions, but his moral compass can still tell him it's the wrong thing to do.
I do believe there are people that have high morals and use those morals to live a good life. I don't think they are the majority though. A lot of the laws that people break they break even knowing it to be wrong because the punishment is something they can accept. Punishment is determined by man and so the repercussions of the crime can change with what the majority want. With religion they had something greater than man that couldn't be overruled.
