Who Kills More, Religion or Atheism?

[The Grand Nudger]

People (and a ton of other things as well) kill people. Fantasy stories about fairies don't have the power to pull a trigger. Lack of belief in faeries, also, cannot pull a trigger. Whatever religious reason is given for this or that it's ad-hoc. The person made the decision, and then justified it after the fact (though sometimes before the act). I can't imagine what reason an atheist would give for killing someone other than "I wanted/needed to" since, by definition, they have no one to blame.
