Personally, I think that is completely your call. I realize that you are a dog going into that hand, as well as AA, but you know perfectly well that people are capable of pushing all in with AJ or other like-hands. I think it's the type of hand you have to decide how you're feeling it. But i'm no expert.

If you're not pushing KK preflop then you're losing money.
