KK in 3-bet pot, A hits the turn. NL2k

I think this is bad you beat a pair of 7s 8s 10s js, who plays them this way? The only hand that call has you beat. Well i mean since u probably were not scared of the 9s, 88 combos the ace is the worst possible card in the deck to hit on turn the check call on flop is fine, but why would u be so aggressive on the turn after u check called the flop when the worst possible card hits. Why not check/fold for a better ev+ spot after the way you played this hand.
