$11 PS - Should I have pushed against this PF raise?

Villain was running low on chips and frequently raising (usually all in) to try to take the blinds. I originally thought to put Villain all in with a re-raise, but decided not to since doing so would have committed half of my chips.

At that level he was VP$IP - 22.5% and PFR - 22.5% (always in for a raise).

Should I have pushed pf or done something else?
