Not committing a crime in the name of atheism isn't the point. And in the case of individuals like Bonaparte, Pol Pot, Mussolini, and even Hitler I would argue, atheism could be said to be part of their crimes as they were very anti-religion. Heck, they were anti-culture which is even worse. Religious fundies may be nuts but even they haven't tried to rewrite a country's cultural system starting from day one (see: Year Zero during the reign of the Khmer Rouge for reference).
