He's a spy if you look in one of the previous chapters some people are talking to him about going undercover.
Dabi is not a spy. Hawks is a spy whom he was just about to kill. Also why would he order the High-End Nomu to kill Endeavor? And kill innocent people?
He's definitely just a mentally insane Stain fanboy who hates heroes.
Yeah I know that Dabi isn't a spy. Idk if mangago is being weird but the comment in replying to in the beginning is one that says HAWKS IS MY FAV IDC IF HES A TRAITOR

Brooo, Dabis black bubble gave me chills. Imagine if he revealed himself (endeavors son*?) to hawks, also I hope he doesn’t DIEE.
