did i play this right in $400nl

villian has been playing loose preflop running about 40/18 and putting a lot of money on flop with marginal hands. he won few big pots including calling someones all in semi bluff with marginal hands in last 10 min. i have about $600 and villian has about $1200. we tangled in blind vs blind before he got the better of me most of the times.

everyone folds to villian(sb) raises to $12 and hero(bb) calls with Kh Kc.
flop was Qd 3d 6d, sb bets $24 and hero makes it $84, then sb raises to $216 and hero moves all in for $380 more to $597.

i called with KK planning to raise sb when he bets on flop(which he will do most of the times in this situation). and was hoping he would catch something and would call me light, but wasnt expecting a reraise. also, what changes if i have Kd in my hand
