"Heidegger, who took Kierkegaard's philosophy further, comes even closer to describing the Punisher: 'Since we can never hope to understand why we're here, if there's even anything to understand, the individual should choose a goal and pursue it wholeheartedly, despite the certainty of death and the meaninglessness of action.' That's sure the Punisher as I conceived him: a man who knows he's going to die and who knows in the big picture his actions will count for nothing, but who pursues his course because this is what he has chosen to do."
