I think the casting team could see what an annoying and obnoxious twat Peter was when they cast him and that's why they cast him!
As much as i detested him it was kinda' worth having him there. Anyone who's that deluded about their vast superior intelligence (



) tends to be infuriating to watch yet equally rewarding to watch fail and crumble!
Him and Alec still giving their stupid loser 'The Shield' signs even at the final was cringeworthy. Idiots!!!
