Who killed the most people Hitler Mao Stalin Pol Pot or the Spanish inquisition or the crusades?

Stalin killed way more people than Hitler... Hitlers death number was about 5 times less than Stalin and only reason Hitler is recognized more often is because he was an anti-Semite and he only targeted certain races whereas Stalin destroyed anyone who opposed his authority. Usually when Stalin killed someone it escalated to killing any connections to that person and the numbers grew. Hitler started small and ended small compared to Stalin.

Hitler by far, although Stalin and Pot didn't do it in small amounts. Let's take a look at Hitler's accounting:

Six million Jews, Thousands of Romanis (Gypsies), A couple hundred Black GI's, Around hundred fifty to two hundred homosexuals At least a couple thousands of Jehova Witnesses, Approximately five hundred Muslims, couple more, couple less, Thirty to forty "communists", and Twenty million Soviets.

These are the ones that have been accounted for, but there's the very much shared suspicion that there are many, many, many more...
