Without fear of retribution

Does the idea that a lack of Divine Retribution makes it harder to have a civil society have merit?

Is it possible that as a lack of "religious faith" grows civil laws lose their ability to enforce behavior?

If you know that the odds of getting caught doing something wrong are pretty slim and if you 'know' there is no Divine accounting, are you more likely to act wrongly?

If you have no fear of God, no fear of the law....what is to stop you from doing whatever you damn well please?
