Villain is loose-passive and he has been calling down most of my C-bets and what not.

Does anybody here push all-in on the river? I can't think of anything he would be minraising here besides KJ (in his range) or a J. Is this a good call behind so I don't lose as much to KJ and for rake control purposes.
