Alex B's utility to the show was yesterday's abuse session with his disgusting pig wife and subsequent freakout via Hassle. He doesn't have the capacity to be better, he cannot grow, he will never be able to escape the hell he's made for himself because he is 100% bitchmade yapping faggot. The moment was presented to him in classic fishtank fashion, box hassle. Win or lose he was offered the ability to reclaim his dignity and he spent hours yapping his way out of it.
Its not a coincidence that the two previous season's lolcows (Jon and Jimmy) also ragequit halfway through the show. Alex isn't the monkey king, he's just the third season's annoying spastic.
