Folding KK pre can be okay in certain uncommon circumstances but you (or at least we) don't have nearly enough of a read on your opponent to decide that this situation might be one of them.
Should've stacked off on the 5-bet FOR VALUE. If he called and showed down AA than it's all right, it happens. Never raise leaving less than a two thirds of your stack behind without shoving.
You should be dying to stack off, given how deep the dude is. If you were like 300 or 400 BBs than it would be an okay play, to 5-bet and tank fold to a 6-bet all in for 3 buy ins.
Analysing the call: You had 1-4 for a call, you need 25% equity to call here. Unless he absolutely for sure had aces, it's a bad fold. Give him a range of AA -> 19%. range of AA, KK > 23% (breakeven call). Range of AA, KK, QQ -> 50% equity (CLEAR CUT CALL. ANY FOLD HERE IS A MISTAKE). Range of AA, KK, QQ, AK -> 57% equity (MUST CALL HERE).
