In respect to atheism and mass murder, Christian apologist Gregory Koukl wrote that "the assertion is that religion has caused most of the killing and bloodshed in the world. There are people who make accusations and assertions that are empirically false. This is one of them."[1] Koukl details the number of people killed in various events involving theism and compares them to the much higher tens of millions of people killed under communist atheistic regimes.
