Chris Brown has threatened violence and ridicules his former protege Kevin McCall for being a closeted gay.
He simply wouldn't be rich without them, and he certainly wouldn't be able to maintain the luxurious lifestyle he currently enjoys. If you're going to roast someone, do it with valid arguments. Criticize them for being talent-less. Shit on their music because it's wack. And given his history, is it actually smart to threaten someone with violence so publicly? Is this boy a dummy, or is he just a fricking dummy?
