Yes, bad things can be done by anyone, atheists included. But I don't know of any atrocities which were committed in the name of atheism. History is littered with examples of atrocities committed in the name of religions, on the other hand. And many of those atrocities were condoned, if not instigated, by the leaders of those religions.
