kills millions without a second thought

Then why didnt darth vader win

I wouldn't classify this individual as the villain. Japan started it by attacking us at Pearl Harbor, and we finished it by dropping the atomic bombs on Hiroshima and Japan. We Americans never asked for World War II.

america was already engaged in fighting before pearl harbor, just didnt **officially** join the war until after

They were not in fighting, unless you cant people in the Philippines defending themselves from Japanese war criminals
