Ooo, he's so wounded. He's been called so much worse in his life. Dabi's amused at Nara'a's frustration, mostly because it's always amusing to see a hero-type get called out with proof on the stupidity of their heroics. Even if this guy had the excuse of simply not knowing the lore behind the monster he was trying to save. (Still... it's a fucking monster. You're not supposed to save a fucking monster.)

And now for the jugular. "Yeah, but by keepin this thing alive-" Dabi retreats away from the swords, lobbing another fireball towards the Bugge's back in revenge for swiping at him. "-and leadin it into the city, wonder how many people ya let die in the name of saving one thing ya shoulda already killed out in the woods."

His tone is musing, but it's obvious he's lancing the other man with the question on purpose. That's the biggest grudge Dabi has against the heroes pushing that mentality in Trench. The price of saving. Nara'a's backstory doesn't go ignored, just not commented on at the moment. "Slit its throat. You've dicked around it enough."

And if Dabi keeps burning it, there won't be any blood left to flow.
