Scott Summers was right.
If the Avengers had worked together with the X-Men in the first place, none of this fighting would have happened. What exactly were Scott's crime? Outside of killing the Professor, Scott only became Dark Phoenix after the Avengers attacked him for the 80th time. The Avengers railed against Scott but they were the ones who instigated this entire conflict. They were the ones who split up the Phoenix and allowed Scott access to their powers. In the end, they pretty much stole his idea about using Hope against the Phoenix.
I don't agree with Scott's Peace at Gunpoint Utopia that he created. But he brought about world peace, something the Avengers never did. As far as I'm concerned, Scott was the real hero of this story. The Avengers, especially Cap and Logan, were just part of the problem.
