[@thewizardguy]The way things sometimes happen here, Magus and Guilt may end up interacting whether they want to or not, and in a way I'm actually kind of interested in how that might play out (which of course would depend on the circumstances of their encounter).
Also, aside from Devil being a Freak, what does Guilt have against him?  He kills the same types of people that Guilt kills (or at least that's how I read his CS), so they would actually be on the same side.
