None of them committed the atrocities they did because they were atheists, they did so because they were nutjob, power-hungry dictators.
Their are lunatics, brilliant people and everyday people in every group. The difference between Atheism and certain religious groups however, is that certain religions have holy books that actively call for numerous atrocious actions, such as the the killing of homosexuals in the bible. To be fair though, most religious people these days distance themselves from the crazier bits of their holy books.
