It's stupid and pointless to compare two characters from two different countries for different periods of time. Sure, Stalin killed a lot. Now, convert those figures to percentages of their country's population, and find the average killed-per-year % from that.

Also, to say that Hitler caused ALL the deaths in WWII is ludicrous. The Japanese were fighting a war before your European one, Nanjing massacre anyone? Also, ever heard of the Soviet war machine's one rifle per 3 (or was it 5) people figure? They also posted machine-guns to gun down people who were running from the battle.

All the Aryan rubbish as well... guess what it's for... SCAPEGOATING! Hmm, never thought of that, did we? The Nazi's NEEDED a scapegoat to blame Versailles and the hell after it, a scapegoat THEY could save Germany from by destroying, ONLY IF VOTED INTO POWER.

As for Stalin's political killings, those were to keep himself alive. In a dog-eat-dog world, if you didn't do that, you'd die and just be replaced by someone else like you.
