I am just forever stuck in this whirlpool of thought. Despite the bomb there's no aggression. Even with the bomb, if it is real, there's no explosion. Only the threat. Quite the contrary. Cooper has no desire to inflict harm to anyone except himself. He let's his hostages go. He doesn't even want them worried. He orders food for the staff. If it is true, he offers Tina some money. He does no harm to the aircraft. There's no signs of distress. He's polite, calm, mostly in control. That only leaves us one option. Punishment and justice.
He's been a good kid, he's learned the issue of fair play, when to apologize. It's evident in his ability on the aircraft with the crew to negotiate, to respect Tina, he accepts facts from the flight crew as believable. Cooper knows how to co-operate with others and it is obvious to me, essential to his revenge. But he's been hurt badly, maybe even worse, he's been shamed and considers himself, whether justified or not, at fault.
Cooper wants vengeance on the banks. They've wronged him. It's evident in the "negotiable currency." There is a good chance, look t the whole ancient ISIS bullshit, "a stain upon myself is a stain upon the whole population." Cooper's revenge could be a family matter(?) The rules of Cooper's justice is to punish who he feels guilty. Exonerate himself without any penalty, which is why he hasn't been caught, and deters anyone from harming him again. Stopping people by "drawing the curtain," "staying up front" to extract a personal revenge in an arena of public revenge, for all to see.
