To me, the critical information here is the read on UTG+1. If UTG+1 is someone who raises light and that MP2 might have bee trying to isolate with less than the values that 14/11 would suggest, then you needed to raise preflop (but you knew that), or, not having raised preflop, cap the flop. Having played it like you did, I call down.

If UTG+1 is reasonable, then folding preflop is not terrible (I'd still raise), and I fold the turn like you did.
