"Does Daredevil go out and kill people" is kinda what the series is about. Also why some problems aren't necessarily solved by punching them.

The show is pretty tightly focused on the story it wants to tell, this isn't Arrow where they just throw characters at the wall and see who sticks, so consequently it doesn't waste any parts of the Daredevil property and doesn't waste time on things that aren't going to eventually matter.

What it does do is put in a large amount of development for all the characters, especially Kingpin.
