The Atheist’s Moral Compass

“If you don’t believe in the Christian God, there’s nothing to inhibit you from committing a crime.  You can be a moral monster!  Nothing stops you from committing heinous acts.”  I hate it every time I hear this!  Atheist are still subjected to the same social and psychological guidelines that hedge any society.  We are still social animals and this trait is the result of evolution, not our choice.  Why is it that Christians feel they have the high ground when it comes to morality?  Have they READ the Bible?  What say you?
