In seasons 1-6 they gave us the outstanding impression he will do whatever it takes for his daughter. Kill anyone do anything. That is simply not true. He did not sacrifice the guard at the shipyard docks, he did not kill the FBI chick when he was with Almieda undercover.... and many other examples. His concience is too...good and has few exceptions. He will keep people alive even when its not best for them to stay alive. He will rescue his daughter but without doing too much harm.
Season 8..
I want to see Jack turn dark in Season 8. Real dark. Kill people, civilians, enemies without hesitation and mercy, whatever. None of this 'they have information i need' ****, just shoot them dead and find another lead.
I want to see Jack kill Chang that bastard, and i want to see the Chineese pay for what they did to him. And i want to see Audry back in action.
