Ugh... Why did I bet this flop. 2-4

[Maier]

Hero has 500 behind on the button. Villian has 175. 6-handed.

EP folds, Villian calls in MP, CO Folds, Hero raises to 14 w KQ spades. SB+BB fold, Villian calls.

(pot 34) Flop: Kh Tc Jc. Villain checks. Hero bets 25 . What should be my action for the rest of this hand. What should have been my action? Why? I thought about it, if he raises, I have to call a raise with a hand that is likely behind, since i cant find any holdings that I am beating, and I will likely pay off til the end. Should I have checked and kept it small?
