It’s very hard to compare one example of genocide to another, particularly when you are comparing events that occurred in different eras. As the genocides of the 20th century proved, technology changes the game by making it easier to commit systematic mass murder. Therefore, comparing body counts or even the frequency of mass slaughter doesn’t truly compare two ideologies.
As a percentage of the population, the Thirty-Years War, at least nominally between the Catholics and Protestants in 17th century Germany, was the bloodiest in history, with estimates of 20% to 25% of the population dying.

Not to mention the simple expedient of having more people around.

As far as I know, Pol Pot’s government “wins” the democide contest, having killed off about 30% of the Cambodian population.
