But if Cyclops is right, then that means that he was trying to prevent the end of the world as shown in Cable's future. Because unlike Captain America and the Avengers, Scott absolutely knows that the world will end if Hope fails. So, who is really taking the bigger risk? The guy who has seen the future and knows that the world will end if Hope fails or the guys who think the world is going to end if they don't take Hope into custody to take her off world?
Humans who guess < Mutants who know.
I hope Cap ends up with egg on his face and mutants rule the world!
