As far as the greatest mass murderers of all time I nominate the aztecs. The aztecs sacrificed 80,000 people in just FOUR DAYS! The aztecs sacrificed up to 250,000 of their own people every year!
In reality, european spaniards actually prevented catastrophic loss of life since the aztecs were such efficient killers of their own people.
