The first sin that Cassidy commits is simply doing something different. When I say the X-Men, I’m referring to Nightcrawler, Archangel, and Iceman. While Chamber and Stacy X are both there, they’re relegated to a few mumbled comments, not direct critical conversation. Looking at the main trio, all have been part of groups that splintered off from the X-Men to approach the mutant issue their own way. Excalibur was similarly European and formed out of the seeming death of the X-Men, but, quickly, turned into a cross-dimensional magic focused sort of mutant team that wasn’t really in sync with Xavier’s mission. It didn’t really engage with The Dream until well into its run, if I recall correctly. During it’s hayday under Chris Claremont and Alan Davis, it was something else entirely. And no one told that crew that they were allowed to do what they did.
The more egregious group is the original X-Factor, of which Iceman and Archangel were both members. The original five X-Men pretending to be human mutant-hunters, feeding into anti-mutant sentiment to save mutants. That’s a fairly large different from The Dream. It shows a certain practicality and, upon reflection, is a fairly direct antecedent to X-Corps. (Has Casey escaped Claremont to fall under the sway of Simonson?) For them to question what Cassidy is doing, particularly on an initially small amount of information, is brash and completely unaware, at worst entitled.
The second sin is the militaristic approach Sean takes. Using Multiple Man as his one-man support staff, there’s a speedy and efficiency on display, backed up by Cassidy’s confidence and knowledge, that gives off the impression that X-Corps is quite adept at what they do. Yet, there’s little that Cassidy does that you couldn’t imagine Cyclops doing. The same decisiveness, the same no nonsense direct talk, the same efficient competence... How could an alternative to the X-Men actually be well run? (I love that Stacy X ominously wondering why all of the people working at X-Corps look exactly alike is never directly answered, leaving the very concept of Multiple Man as another criticism or suggestion of something sinister at play here...)
The third sin is that the X-Corps uses former villains as the “Bastard Squad” of field operatives. Avalanche, Surge, and Blob are all put into play with Avalanche taking the lead and saying things like “YOU WANNA LEAVE A JOB LIKE THIS TO THE PROFESSIONALS.” The X-Men express deep concerns over employing former villains as if, firstly, Sean Cassidy isn’t one himself; secondly, Emma Frost, his former co-headmaster, isn’t one also and currently a member of the X-Men in New X-Men; or, thirdly, the long, long history of villainous mutants joining the X-Men when the mood suited them or Charles Xavier. Magneto was once in charge of the school, after all. Perhaps, it’s that the villains don’t seem ideologically motivated... it’s never stated directly, but the implied reason for their presence and compliance is that they’re employees. Their stake in Cassidy’s new group is a financial one and that’s somehow less than acceptable. Easy for the beneficiaries of Xavier’s wealth – or Archangel’s own wealth – to pretend like money could never be a legitimate motive. It may be the only legitimate motive for men like Avalanche, Surge, and Blob at this point, honestly. They’ve all heard the sales pitch for The Dream and turned it down; giving them a job to be ‘good’ is the better of the available options.
All of their objections seem to boil down to the first one: who is Sean Cassidy is decide on his own direction for human/mutant relations without permission?
It actually reminds me of a trend that I noticed at DC during the late ‘90s/early ‘00s where it seems like every few years, one of the ‘Big Seven’ members of the Justice League would ‘go rogue’ and try to ‘make the world a better place,’ bringing them into conflict with the rest of the JLA. Superman, Batman, Aquaman, Wonder Woman... each took their turn deciding to act upon their personal morality and it was always greeted with selective amnesia of the previous times this happened, and always with a unified moral outrage that anyone could do such a thing. It’s about a collective moral adherence to the status quo, which is an external mandate from outside the world of the superhero comicbooks. That’s why it always feels like my reading of this story is wrong. I can’t believe that Marvel would want me to think that there’s a point to the X-Corps and that the X-Men look hypocritical and unaware of their own history and actions.
Early on in the issue, Nightcrawler talks about how they’re all on the ‘front lines’ of human/mutant relations and asks Cassidy, “IS THIS THE MESSAGE WE WANT TO SEND?” His response both sums up his perspective and the exact problem that the X-Men have with it: “THIS IS THE MESSAGE I WANT TO SEND.” That singular perspective that goes against the collective, against the singular influence... we can’t have that. Right?
