Authorities employing Christian, Islamic, Marxist, Nazi and democratic ideologies to the end of world domination once and again resorted to mass killings. The death count is biggest in Marxism and National Socialism, the smallest in Christianity and Islam. The democratic government will never set the count at the same minimum level of Inquisition, Crusades or jihad. But the death count for the case of democratic government is not yet complete. And it can easily exceed the martyrology under Marxism and National Socialism.
