If UTG just sat down I think it is safe to assume he does not know the other player is tilting. In that case I think you have to lay this down on the turn.

I might check/3 bet the flop to get the most information out of UTG. If he caps I maybe peel for the turn but it looks like you lost to KK.

He picked up a flush draw on turn, I don't think he can fold there. Fold on the river is very safe though for the reason you said - I just sat down and have no idea if MP is tilting or not.
