As far as the comedian guy who was Guantanamo'd, I believe a lot of what he says and wouldn't put it past MrBeast to do an insane stunt like that for a video, but he doesn't come off as the most reliable narrator in the world or the most sympathetic protagonist to use for building a case of "Jimmy is le bad". For one, he's a standup comedian and they're all known to be liars and exaggerate their stories. He also seems incredibly manic in a way that's hard to follow what he's saying. (I'll be charitable and assume this is him processing something that is clearly pretty traumatic but still could have been cut down in editing to be more cohesive), and his "hipster dirtbag" look of mustache + mullet really does not endear him to me.
