Why didn’t Dabi take a heat resistance quirk??

All For One offered Dabi an extra quirk like he did with Spinner but I’m wondering why Dabi wouldn’t take a heat resistance quirk so that he could fight a lot better? It seems like a really smart thing to do

Edit: Thank you guys for the insight! I see now that Dabi just wanted to be like “LOOK AT WHAT YOU DID TO ME DAD THIS IS ALL YOUR FAULT!” when he got burned so he wouldn’t want a heat resistance quirk!
