Being passive with TPTK

[DBowling]

Not a bad beat post, i was looking back at this hand i think i should have raised the turn, but im not sure why.
Possible reasons to raise:
Push out a better hand.
Charge a worse hand to outdraw me.
If i dont raise, but he would have called me anyway, i have commited a mathmatical tragedy.
A heart might kill my action.

My reasons for being passive on the flop and turn were:
Im way ahead of a hand like KK, QQ and i dont want to scare him away.
Im way ahead of a hand like AQ, AT.
Im too far behind a set or AJ to get away from my hand if i reraise and he pushes.
CAN YOU BELIEVE THAT AFTER 13,000 HANDS AT 6MAX, AKs IS MY BIGGEST LOSING HAND? no? well neither can i. maybe you will after you read this HH
