All that said, what really jumped out at me about AvX this time was the subtext that, even before the conflict with the Avengers started, Cyclops was well and truly a broken man. Losing Jean again had destroyed him inside, and all he had left to hang onto was his faith in Hope being the mutant messiah. That's what led him down the path to being a fanatical zealot for whom the ends justified the means. On some level, through Hope and by uniting her with the Phoenix and restarting the X-gene, he thought he could get Jean back. Or, at least redeem her loss (and his) and give it some meaning.
It's all right there in a bit in
Uncanny X-Men vol. 2 #12:
An instant later, at an abandoned Hellfire Club safe house, Magik teleports herself and the Sub-Mariner in. Colossus, the White Queen and Cyclops are waiting, and Cyclops announces that the goose chase is over, for Hope split her signal, but now they know her real destination. ‘The girl shows wisdom’ Namor remarks, before asking where she is. ‘The moon’ Scott reveals. ‘The Phoenix. The moon. Familiar…’ Colossus remarks. Magik opens a portal, and as the five X-Men enter, Cyclops replies that he knows, and that it scares him. ‘I don’t like the echoes, either. But you know what? It’s a second chance’ he states. And as the Phoenix Force hovers over the moon, Cyclops declares ‘This time we write a happy ending’.
Scott's actions throughout the event--all the posturing, all the violence, all the rage--were ultimately driven
by his grief.
IMO, the whole thing should've ended with Hope finally defeating Scott by sending him to the White Hot Room to be with Jean in exchange for surrendering the Phoenix Force. Plot-wise, it would've concluded the event more definitively and tied off Scott's tragic character arc from Morrison onward in a thematically conclusive way. It would've also provided a cleaner break for the X-Men going forward than all the RightClops malarkey that followed.
