So Atheists: Who are you people accountable to? Or does your doctrine dictate "random" & "chance" behavior?

I'm accountable to me, and the society I live in. If I break the law, I expect to be arrested, tried, and if found guilty, sent to jail. I don't need a man in the sky with a heavenly carrot and a hellish stick to regulate my behavior. People who need that, and say they are being good people are just hypocrites - they are only behaving so they can get the big brass ring come checkout time. It would be the moral equivalent to prostitution if there really was a god.
