C'mon! Superman kicked Hitler's butt.

Hitler was a piker compared to Stalin. (Although Hitler did better on a day by day bases and gets points on sheer organized murder).

And if you want to go on ratios of Civilians killed to total population; Pol Pot was the Grand Master. (The jury is still out on Rwanda, it may take the prize)

Superman is an American. He can't declare war on his own. Since neither President Roosevelt nor his successors declared war on the USSR he had his hands tied (though I'm sure he still helped out in some covert actions).

Oh, and before you mention Osama bin Laden, it is now Batman's turn.
