Spoilers for Way of X #1 below!
One of the longest and greatest battles in Marvel history has ended as a new X-Men title Way of X sees Magneto admit that he was always wrong. Dedicated frenemies Charles Xavier and Erik Lensherr's ideological struggle has given way to some of the most iconic comic book stories of all time. While both have always had the noble goal of mutant equality in mind, they very famously have used different means to reach that end.
Professor X always pushed for peaceful coexistence between human and mutant kind. Magneto sought for his brethren to take their place in society through more brutal methods. So it went for decades (with little periods of team-work between the two camps every now and then) until the two leaders established the mutant nation of Krakoa. Mutants finally have a home, culture, and even a language of their own. The infighting has stopped, and Magneto has made a confession.
Magneto admits he is wrong in Way of X #1 by Si Spurrier and Bob Quinn. Following a prank by Nightcrawler that references the Master of Magnetism's violent past, Magneto launches into an impromptu speech to a small crowd of mutants. In a shocking turn of events he acknowledges that he was wrong to fight Xavier and that the infighting between mutants held back the entire race. After all, look at what they have accomplished since they started working together. Mutant synergy has made Krakoa a post-mortal society.
It's a rare moment of reflection from such an egotistical character. But it's not just reflection, it's regret as well. Magneto has never been a heartless psychopath like Thanos or Doctor Doom. He's a Holocaust survivor who's seen humanity at its very worst and simply doesn't want what happened to him to happen to any other mutants. Above all else, Magneto just wants to protect his people. So when he talks about how much mutant kind has been able to move forward since he put aside his differences with Professor Xavier, you know he means it.
While Krakoa's very existence may be embodied by the sense of mutant superiority Magneto fought for, the reality is that the island is a sort of third way solution between his and the X-Men's ideologies. While the mutant nation might not have the warmest of relations with humanity, things aren't exactly hostile either. Magneto admitting he was wrong is one of many huge developments to have quietly come about since House of X and Powers of X made their debut in 2019.
