Easy fold preflop with KK ?

So there were about 60 players left and 15 got the money. ~3k € to the winner.

Why would i want to risk my big stack at this point of the tournament ? Its only freeking level 5 and if id fold id still have a monsterous stack.
And would you really, as the Villain, re-re-raise the only player who can hurt your stack BIG with QQ or AK here ?? I doubt that a lot.

Villain had about 3000 more then me, so i really would hurt him bad if i won the hand...
