If he's trying to rep nut flush (or straight-flush) he probably needs to jam and if he thinks he's raising for value he's out to lunch.
Pretty sure the Villain thought, he had the best hand and was raising for value. Which is really optimistic, since the only worse hand, that might bet pot on the river and then also call a raise, would be trips worse kicker. Which he strongly block. Far more commonly this pot sized bet will be a flush or a bluff, and then it obviously makes no sense to raise, since the bluffs will always fold and the flushes always call.

I'm certainly not re-raising with a paired board and a 4-high flush. I wouldn't have bet there either...
The pot size suggest, that both the flop and turn got checked through, which makes it highly unlikely, someone has a boat here. So a small flush is a clear bet for value, but I might not have bet full pot. With that sizing Hero pretty much only target trips, and I would want to give myself a chance of getting hero called by some random two pair as well.
I would also not have checked a 4 high draw on the turn, when the flop got checked around. I would have bet out and tried to take it down without having to hit the flush. If Hero is not betting the turn with this hand as a bluff, then most likely he is never
bluffing at all, which is a mistake. You need to sometimes try to take down pots, that nobody have shown any interest in.
