Rules of right and wrong ensure that our species continues to exist. Behaviour which is beneficial to the group is sustained, and that which harms the group is selected against (we kill the offender, or put them somewhere where they won't be able to reproduce, like prison). Behaviour which we now consider "bad" is that which harms the group, and that which harms the group tends to debilitate either ourselves or our offspring in the long run. That's why the majority of people don't go around stealing, raping and murdering. That's where morality comes from. We don't need the idea of a god to instruct us, it‘s just common sense.
Don't get me wrong, people still do bad things; however, some system of laws and morality has existed in every culture, and arose because of the group's need to cooperate.
Besides, religious people do bad things ALL THE TIME. Spanish inquisition, anyone? And, Hitler thought that he was doing God's work. Yeah, religious people are always sweethearts.
