The thought started in my mind when I learned that atheists, on a per capita basis were grossly under represented in prisons and the committing of crimes. It seems that religious people just do bad things more often than atheists.
I think it is the idea of confession, forgiveness and absolution, that is responsible for Christians behaving badly. After all no matter what they do, they just need confess and be absolved and they can feel liek they are "good" again.
As another user on this sit eput it, they can be a dick/asshole six days of the week and be absolved on the 7th day without making any restitution/reparations to those they actually have wronged.
At least AA (Alcoholics Anonymous) and other twelve step groups has as one of its steps to try to make things right with those they have wronged. Religion makes no such requirements.
