I'm talking about his entire stance since X-Men: Schism.
When Wolverine is like nah b I can't **** with you, something is wrong
To me he just kept going further and further away from what made him a hero and leader which again was fun to read and watch
As for AvX, I mean they were gonna fight so I can't judge much either way cuz it was an event revolving around that but as far as the Avengers stance it made sense cuz they got a heads up this time. The Phoenix force is destructive, genocide/planet killer destructive. It was on a path where it destroyed several other inhabited planets heading for Earth.
EVERY time it comes to Earth it's the same ****; somebody gets cosmic power, they try to fight it, they think they're controlling it, they go dark, ppl or an entire race dies, then that person has to sacrifice themself just to get rid of it. I don't think there's a Phoenix story where most of that doesn't happen
The X-Men know this. They're experts on it but for some reason this time Cyclops has a hunch or wants to rely on a leap of faith that the Phoenix this time is coming to make Hope the host and save all mutants.
Sorry but there's no reason the rest of the superheroes should believe in that outside of those that have time traveled and saw that future. Forget that in the end he was righ. That premise isn't enough to risk mankind and the entire planet.
So I totally get the reason why they fought. Although the Avengers plan ended up being capturing Hope, training her themselves, and her being so fed up that she teamed up with the mutant killer in the first place and attempted to kill the Phoenix
Back to Cyclops, he was obviously in the wrong in the end. To me that was the time to make him go full anti-hero/villain. He killed the man that was the reason there was a X-Men in the first place. I'm hindsoght, didn't enjoy the Bendis run that much if I focus on Cyke's progression.
