Which dictators was the most brutal, and why?

If we go by total death count, Mao Zedong is the most brutal dictator of all time.

Explanation:

Mao Zedong was the dictator of China from 1949 until his death in 1976. As chairman of the Communist Party of China, he was in charge of most Chinese policies at the time.

Most of his policies are recognized by historians as having been not only an economic failure, but also an humanitarian failure, because of the millions of deaths that these policies brought, especially the Great Leap Forward and the Cultural Revolution.

According to most historians Mao Zedong caused the deaths of around 50-100 million, making him by most estimates, the dictator that caused the most deaths in history.
