It sounds more like Daryl's own problems, his own ethos, than he cares to admit. You keep going, because you don't know how to stop. The major difference, it seems, is that this lady has a plan for when the end finally comes. Daryl's only goal, himself, is to go down swinging.

"How d'you wanna go?" This is more morbid than he usually cares for, but he appreciates the distraction. Anything but thinking on what he said in that room, to that awful woman.
