chasing, is a normal word for heroes nor villains. Your biggest enemy is Dabi, you always annoyed by the way he's mocking you. But at this moment, the table had turned. Now here is Dabi, front of you injured. You wanted to mock him, so you offered a help. In 'mocking' tone.

"Fuck off, brat. I don't need your help."

Dabi scolded, knowing so damn well he can't even stand up by his large wound.
