The following contains spoilers for Sins of Sinister #1, now on sale from Marvel Comics

For all his many faults, Charles Xavier has always tried to keep good intentions close to his heart. The dream behind the Xavier School was to make a place where mutants could feel safe as they learned who they truly were. It was an inherently optimistic place for the X-Men to grow which opened its doors to numerous generations of young people from across the world. Despite all the moral lapses he and his former students have made, for all the villains and monsters they've survived, Xavier's dream was always one based on hope.

That's what makes the corruption of it in Sins of Sinister #1 (by Kieron Gillen, Lucas Werneck, Geoffrey Shaw, Marco Checchetto, Juan Jose Ryp, David Baldeon, Travel Foreman, Carlos Gomez, Federico Vicentini, David Lopez, Joshua Cassara, Stefano Caselli, Bryan Valenza, and VC's Clayton Cowles) so horrifying. Relieved of his already problematic morality by Mister Sinister, Charles Xavier's dream is effectively every worst-case scenario possible for the future of the Marvel Universe. In a story about corrupting the Marvel Universe into Sinister's image, the twisting of Prof. X's original intentions is the most tragic.

A Corrupted Xavier Helps Guarantee Sinister's Victory

X-Men Sins of Sinister Xavier Chimera 3

As one of the Quiet Council members killed by Mister Sinister ahead of the event, Charles Xavier was promptly resurrected along with Emma, Exodus, and Hope. But without Hope in the circuit serving as a negation to Sinister's mental trigger, the four were revived with Sinister's influence and best interests at heart. As a result, Xavier and his compatriots quickly endeavor to set up the villain's victory. Within a decade, almost every other major Marvel hero has been dealt with or contained, and Sinister Xavier -- alongside Emma, Exodus, and Hope -- has helped ensure a Sinister-dominant world.

The result is the corruption of many of the X-Men's most heroic figures. Wolverine stabs allies in the back, Cyclops lures Captain America into Sinister's clutches, while Forge and Hope effectively render Krakoa brain-dead. Xavier's corruption feels particularly brutal, however, as almost all his positive intentions have crumbled. Xavier's long-fought people who've believed mutants should rule over humans. Now, Xavier casually uses his telepathy to help create a world where mutants rule everything and everyone. Any dream of human/mutant unification has been replaced with elimination and assimilation. The importance of choice is replaced with a psychic scalpel. What little ethical concerns he had were lost, and it's proof of how horrifying he can be.

Sins Of Sinister Destroys Xavier's Family & Dream

X-Men Sins of Sinister Xavier Chimera 1 (1)

Xavier's family relations have always been distant even in the best of times, with characters like Juggernaut, Legion, and Xandra having very mixed feelings about Charles. But without any more of his morality, this new Sinister Xavier is content throwing them away. Juggernaut is lost forever upon being used as a blunt instrument to destroy Thanos and Xavier's psychic abilities are implied to have helped usher Cain Marko willingly into a one-way mission. Clones of Legion are produced to break entire worlds, the ultimate rejection of his son as his own person. The larger Marvel Universe is hinted to be the next target of the increasingly ambitious Sinister expansion, suggesting Xandra and other cosmic forces might become fodder for the mutant's mission.

Xandra may have even been corrupted similar to one of her dark multiversal counterparts. Xavier's embrace of his terrifying potential comes clearest when he tries to take mental control of Storm as part of his power plays. The worst blow is the school itself. A place where young mutants found themselves, Sinister's ultimate insult to Xavier comes with his corruption of the Xavier Institute School Grounds. The school has been largely left in disrepair in the Krakoa Era, only appearing sporadically. But now, it serves as an unglorified Chimera factory. The (long-teased) first generation of genetically-altered mutants is created at the newly converted labs. The way the school once molded students into heroes, now serves as a way to literally mold together new mutants with singular purposes. It fully removes the humanity of the X-Men and the growth inherent to it, leaving Xavier's dream cynical, cruel, and heartless.
