It was a uni society. Obviously you'd pick your friend over someone slightly better. I would encourage being a good friend

Both him and the other guy were there, which means he was also elligible for the position. This is an unforgivable breach of the bro code and you shouldn't encourage it

You have broken the bro code. Your homie was well suited for the position and you knowingly screwed him over. Honestly you're a terrible "friend"
