AA vs KK vs QQ

[Tomatoes]

I thought this hand played out rather strangely and would be interested in any comments on it.

3 questions about this hand:
Did QQ butcher this hand by bloating the pot preflop?
Did KK make a huge laydown or a huge blunder? (the guy only said he folded kings so we don't know for sure, but let's assume he is telling the truth)
Did AA make a mistake by not raising at the first opportunity?
