Oh I know not everyone is out to be nice. In fact a demon would be ashamed to act nice. But then most the time that's just them sort of being backwards with their emotions. You know they're really complicated? Like Mao, he's a demon and he's my friend, he always calls me slave, or says backhanded things, but I know what he really means under it all. He just can't let himself be honest because he's a demon.
