[Closed] NL5 letting an opponent beat himself

I had some history with this player. He is the type of player who likes to throw money away whenever he has any type of pair... forcing better hands to fold. However, whenever the aggression is taken away from him, he folds.

Was "letting him hang himself" the right move? I re-raised on the flop with a similar hand before and was told be veriz that re-raising on such a dry flop means I'm forcing all weaker hands to fold and so this isn't the best ine. So, I called the flop and once I made the full house decided I would shove on the river.
