The Prophet of Disdain is a Prophet who was hated people who probably was or wasn't going to be in Halo 2. Some people think that some people assassinated him for hating a lot before Halo 2. Though, if he's like the other Prophets who do the opposite of what their name says, he should have hated himself. So, it is possible he committed suicide before Halo 2 because he thought of himself as a "swine/asshole/pig/false prophet" or one of many other things he probably thought of himself.
