That's true. The Nazis were purely evil, yet in an antiseptic way. Because of their belief in their supposed superiority, they tried not to behave as animalistic savages and barbarians. The use of gassing to exterminate the Jews was concocted because Himmler wanted a bloodless way to commit mass murder. At one point, he personally witnessed Jews being shot in the back of the head and dumped into a mass grave, and it made him vomit. So he came up with a way to kill with a veneer of sophistication. The Ba'athists, on the other hand, got their jollies by being as barbaric and medieval as possible. While the sight of blood turned Himmler's stomach, Saddam and his mafia sadistically enjoyed the bloodiest of atrocities.
