Here he goes with the weapons again, as we see Frank Castle locked and loaded, and ready to "take care of the scum that killed family." Although it was apparent from the image of him and his daughter, and the carousel, this is the first time in the trailer that his purpose - the thing that caused him to be the Punisher - is revealed, confirming that this is an extremely personal, revenge-driven mission he's on. The question left is just who is responsible for their murder. In the comics, it's because of his family getting caught in the crossfire of a mob war, and that is certainly something that would translate perfectly well to Hell's Kitchen. If there is a boss more directly responsible, then it also leads to the possibility of an actual big bad, which would subvert the expectation of this being Daredevil v Punisher.
