Have you noticed that Geto

became arrogant when he became a villain unlike Kenjaku who was of course already a villain? Kenjaku gives the feeling that he's truly confident but not Geto. I don't mean he's insecure...maybe he was... but it looks more like arrogance. Same for Mahito. He's evil. He's cocky but I don't get the impression that he's arrogant.
