Fail List is Fail.
Stalin wasn't really a conqueror per-se. He killed a lot of his own people more so than destroying a whole race on his way world domination.
We can argue all day, but bottom line is we can go through every culture throughout history and find terrible, evil rulers/conquerors who have left massive body counts for world domination.
But Genghis Kahn is by far the worst. He killed nearly 40 million people, 4 times more than Hitler. In fact, Nazi Germany's blitzkrieg was a modern form of warfare that Genghis Kahn himself developed in 12th and 13th century.
