In answer to your actual question, if a particular player was to call a 5X raise being 1st to act on later streets then NO i don't think there is much chance at all that they are going to fold a hand that has hit the flop twice. He most probably believed he was miles in front on the turn while putting in his money anyway (hence the insta-call). It wasn't bad play by you just horrible river.
