Middle Set facing lots of aggression, huge 3 way pot

[Soul Rebel]

This was one of those hands where nothing about it felt right, I hate my play on all streets. It was at the end of a long session, and I had been playing about half an hour too long. Anyway, the BB is donkish, he'll give me his stack with TPGK, he'll draw with horrible odds, and he's had a half stack for a while. He hasn't done anything too ridiculous though. MP is solid, a little loose pf, but decent and aggressive postflop.

My thinking at the time was that the flop could not have been safer for middle set, with no draws, and KK would have been raised PF. I still regretted checking it in a 5-way pot as soon as I did it though. On the turn, I called BB's bet thinking there was a good enough chance that MP or the button would bet, and I could raise while keeping BB stuck in the middle bleeding chips. MP's first raise could easily have been very light, he'd do this if he picked up the oesd, or with air. When BB reraised, I knew I had him, since he badly misunderstands hand values. MP's push is a tough decision, because he definitely has a hand, and the only thing I can put him on is 88, or a slowplayed 33. He might do this with K8 occasionally, but I dont think he'd do it often enough against 2 raises to consider it here. Comments on all streets welcome, thanks in advance for the help.
