At least they're keeping Don Cheadle and not getting another Rhodey. I saw somewhere that they were going to run off the (2005) 'Extremis' series. But I'd rather have the Mandarin, been wanting to see technology vs. magic since the first movie.
As long as Star-Lord is the leader, and the whole team is in it, it might be ok, but they will more likely ruin it by playing to much towards Rocket and Groot. They are great characters but they are comic relief. Maybe they will be fighting the Universal Church of Truth, which would be cool, or possibly be the starting point towards a Infinity Gauntlet/War/Crusade crossover.
She will be forgiven, but it will haunt her, like Hank's lapse of judgement and Spider Woman's name being ruined by the Skrull Queen. Other heroes will always have a different view of them, some will forgive, others maybe not. But she shouldn't be blamed for it, do you blame some one that has gone insane for what they've done?
