If the pope in infallible then Vatican 2 wasn't a mistake. You'll either have to accept the pope is fallible and thus Vatican 1 was a mistake or 2 wasn't a mistake and you ought to listen to your infallible master.
A true pope is infallible because the Holy Spirit protects the teachings of the Church. A heretic even if it pretends to be a pope is a heretic, not a true Catholic. Dont be fooled by the externalities. Check the dogmas they profess. By their fruits you will know them.
