Overpair Facing Ball-busting bet on the Flop--

I don't know how to post hands here- but I'm going to try to get the info across. Background- this is a 6-handed home game, basically a ring w/ rebuy (chips = real money) but the blinds do increase by the hour.
Hero is TAG, Villian is toughest LAG at table. Blinds .20/.40

Villian is SB $18
Hero is on cutoff seat $13

Hero is dealt KdKh

UTG- fold
MP1- limp / call
Hero- raises to $1.00
Button- fold
SB (Villain) - call
BB - call

-$4 in pot-

flop: Jc 10s 5h

SB / Villain - leads $3.5
BB- fold
MP1- fold
Hero - thinks, calls $3.5

turn: Jc 10s 5h 4d

Villain- bets $4.5
Hero- thinks, thinks (for very long time) ...

Betting Pattern- Villain bets with weak holdings, prob. wouldn't come out so strong on flop with JTo, especially from EP. (he likes to trap)

Tells: Villain talks a lot with good hands, acts distraught and confused over opponent; this time, silence.

Hero - puts villain on AJo and calls, figuring the $4 All-in raise would be called anyway.

River: Js
Villain: Puts me all-in

Hero Folds.
Villain shows J9o

Comments? Was is a mistake to go after a huge pot with a mere overpair, even if i figured I was ahead?

raise the flop. It would tell him that you don't care if he does have a J because you have it beat.

is this ever a bad idea?

All you can eat on the turn baby.

push the turn.

Flop call is fine, raise is fine too, depends on opponent and your image. Push the turn everytime and call river as played.
