I think raising the turn is mandatory in this spot for the reasons you stated. Not raising the turn is borderline criminal. First of all you still have a pretty big hand on the turn, and your raise can knock out UTG with some hands that could possibly win a showdown. On the river I would check as it seems villian isn't going to fold a pair here. If the player was the type who might possibly fold a pair I would bet. Also If villian donked river I would call after raising turn.
