[Vash doesn't think it was a waste of time, though. He's unhappy that Dabi didn't listen, of course, and he's disappointed he didn't react in time to pull the man out of the way regardless of Dabi's choice, but he'd never consider it a waste of time to have tried to convince him otherwise.
But that line of argument probably would be a waste of time. Instead, he takes a different tack:]
If that's the case, why keep walking with me?
[It might seem like a non-sequitur, on its face. But from the other man's point of view, Vash's presence must be a hindrance at best--injured, missing an arm, and unwilling to fight to kill. Even in his irritation in being "preached at", he hadn't attacked Vash, nor tried to get rid of him since, despite his pointed questions.]
