Villain is very bad, runs at about 45/5 over 40 hands.

1. Villain limps in mp, and it folds to me in the BB with [8c]. I raise to $4.5 and villain calls.

2. Flop [8s][4c], pot $9. I lead $7 and villain calls.

2. Turn , pot $23. I lead $17 and villain raises to $42.....

Do I give what seems to be a passive player credit here, or am I all in anyways? I feel like he can easily be limping J9 or QT, with a much lower chance he has something like AQ and thinks it's the nuts, but who knows.

Also is it good to raise preflop against this type of player?

I fon't like the raise PF. I think that [Tc] is too weak to be playing that strongly OOP, In position a suited one gapper for a raise maybe ok.
