Hitler - 20,946,000 deaths - not his own people. Never executed his generals, only dismissed them, excluding the bomb plot. Right wing
Stalin Killed 61,000,000 of his own people. Executed enmass his army officer corps. Sent front line Russian soldiers to Gulags after the war (as they had seen the west) .. Left wing
Mao Killed 72,000,000+ of his own people .. figure of deaths is probably a lot higher. Left wing
