This was very well-done issue. I'm absolutely loving Judgment Day because of how it delves into character issues.
The theme of this issue with culpability, and Jean is such a good choice for that. She's done so much good over the course of her existence, but there's one dark blot that can never be forgiven. Nor should it. What she did to the D'Bari was heinous, even if it was with the nudging of the Phoenix. I think of it as similar to drunk driving. Someone might be drunk, but they can make the choice to go behind the wheel. Even if they dedicate to their life to preventing drunk driving, it will never be enough if they t-boned and killed someone.
I also like how it touched on the Quiet Council. Although not explicitly stated, the first thing I thought was Jean choosing to be the X-Men because there are fewer difficult choices there. To quote Hamilton, "Winning is easy, governing is harder." In many ways, it's easier to rack up the good wins. Being a part of a government entity has more culpability when things go wrong. The X-Men are the unquestioned Good Guys. Although there are clearly good people on the The Quiet Council, by nature of voting the Quiet Council sometimes does Bad Things and have to make decisions that can lead to the harm of others, even if they believe it is for the Great Good. It's easier to be the saint on the X-Men.
I'm curious to see where Jean goes from here and what she does with the judgment. With some characters who failed, I feel like they sort of knew it was coming. How does failing -- which Wolverine notes Jean isn't used to -- impact her moving forward? Right now we're in the righteous fury stage, but will there be more? What stood out to me in the end was that Jean focused on the hypocrisy of the Progenitor. In some ways, she made it about herself, which was an intriguing touch.
