So I may have ♥♥♥♥♥♥ off some NPCs and I discovered it affects shopkeepers as well. Is there a way to reduce their grudges or are they stuck like that for the rest of the game until I make a new game?

Edit: Nevermind I found Heydeez and I can remove grudges by doing this. Although there's now a trophy for defeating 'em.... Does Heydeez respawn?
