I love the scope of NA. It's what big idea superhero comics should be, IMO. The heroes within are presented with some very weighty moral choices, but do we all agree that the Illuminati is doing the right thing? Stark and the boys are right to take all of these precautions and to be prepared to execute them. Captain America presents an opposing view, but it appears that Cap's "plan" is the same as that of the Great Society, to basically hope everything turns out alright without considering all options and measures. This is the end of everything, after all.
Do they remain moral men and let the Earth die if they fail or do they use every option available to them, including the "unthinkable"? How long before the odds catch up to them?
The Illuminati have done terrible things, and possibly more horrible things to come before this is all finished. It's already caused sacrifice and cast shadows upon their souls (those which still have them). The choices and actions they've taken have obviously burdened them to a great degree, but what other choice could they make? What would we ask of our heroes so that they might save us all?
