Yeah, as much as I love the character is captured etc trope Fisk really isn't the kind of guy to draw out a person's death unless needed. he kind of walks a fine line between not wanting to make people suffer who don't deserve it, and unleashing hell on earth for those who (in his mind) do deserve it. And he's not shy about that extending to the loved ones of those people he wants to punish. It's all very contradictory, but that's what makes him an interesting character.
