Does the villain make the hero -- or does the hero make the villain?

That's the central question in the trailer for the second season of "Daredevil," which introduces us to a new big bad in the form of the Punisher (Charlie Cox), willing to kill.

"I hit 'em and they stay down," the Punisher snarls. He thinks Daredevil is "a half measure" and it's up to him to enact vengeance in the city.
