Many wars have been fought and any people slaughtered in the names of Allah/God. How many in the name of Satan?

Christians and Muslis bang on about the evils of Satan but they are the ones who go to war and slaughter each other in the names of their Gods. Who ever heard of a people going to war in the name of Satan? And, by the way, don't even try to mention Adolf Hitler; He had Muslim Armies and Catholic approval. Jews don't get of the hook either because they started this whole religious war trip (see Old testament)
