Sorry, Mao's still got the Taiping rebellion beat by a factor of 4 (I went with the highest estimate, 78,000,000 to fit all other killings he might have done under the folds). And then if we're including wars, Korea, Vietnam, Greek Civil War. Communism, in its short 170-ish years, has been able to kill more people than any other ideology. Mao plus Stalin plus Pol Pot is 90,000,000 is. For context. WW2 killed around 72 million. So if you're asking me which I would rather have the government totally insulated from, Communism, in a heart beat. I would rather live in Iran than North Korea.

It's not just bad ideas that kill people, you know. 400,000 corpses litter the great wall of china, built to (successfully) protect the empire from rape and murder at the hands of mongol raiders.
