It sounds like LuckyCharms' natural state is asshole. His rant, if true, has everything to do with his natural state and, likely, very little to do with pain.
I've been dealing with a kidney infection from hell since Monday. Yes, even fictional spirit-guides can get very real kidney infections. Through all of the pain, and there has been a lot, I haven't been an asshole even once. That's primarily because my natural state is not asshole like LuckyCharms.
