Despite claiming to help his fellow mutants, Magneto has no qualms on attacking and even killing other mutants who stand in the way of his anti-human crusade.
In X-Men, he is willing to sacrifice Rogue but not himself in the advancement of his cause. Beautifully called out by Wolverine, who tells him: "You're so full of shit. If you were really so righteous, it would be you up in that thing." The biggest irony of that is, if he had been willing to sacrifice himself, the plan would have worked.
At the climax of X-Men: Days of Future Past, his past-self has his most blatant moment of hypocrisy in the entire film series. After all the bravado both before and after about protecting mutantkind, he deliberately pits a Sentinel against Wolverine and Beast, ordering it to "do what you were made for."
In the plane, he calls Xavier out for abandoning the mutants out there to be killed or experimented on. Given how X-Men: First Class ends, Xavier can reasonably say that Beast, Havok, Banshee and himself (who was newly shot in the spine) could have easily ended up as guinea pigs for either the US or the Soviet Union because Magneto left them stranded in Cuba with no transportation.
In Dark Phoenix Magneto rolls his eyes and scoffs at Xaiver's attempt at de-escalation over the Roaring Rampage of Revenge he and Beast are having over Raven's death saying: "You're always sorry, Charles. And there's always a speech. But nobody cares anymore." While Erik makes a good point, it's still very rich to deride someone for being "sorry" when he's The Atoner still very sorry for his past actions himself. It is also extra rich to mock Charles for making speeches when six previous X-Men films have shown Erik is constantly making grandiose speeches himself.
On the topic of Dark Phoenix, Erik goes on an Unstoppable Rage at Jean killing Mystique and while the performance sells his grief and anger, his antagonism at Jean for it is completely hypocritical. In X-Men: Days of Future Past Erik actively spent the latter half of the movie intentionally trying to kill Mystique himself (even putting a bullet in her leg) whilst in comparison Jean killed Raven by pure accident. Even the counter argument that Erik was attempting to kill Mystique because her actions as a villain cause the Bad Future for mutantkind, just makes Erik look even more hypocritical since he's one who sent her on the mission to kill Trask and shaped her into a Dark Action Girl in the first place.
Shaw says "We don't hurt our own kind." A few scenes later, he kills Darwin and later on presumably orders his team to kill Xavier's X-Men during the Cuba battle; he also isn't averse to beating up Erik.
Charles uses "mutant and proud" as part of his pick-up lines, which are basically a very erudite variation on "you have pretty (insert trait here)", in the presence of his adoptive sister, who has been actively discouraged by Charles from taking any pride in her mutation.
At the beginning of the movie, Shaw denounces the Nazis and their practices, specifically citing their racism and antisemitism as stupid and shortsighted. This is in spite of the fact that his end goal is to annihilate the entire human race on the grounds that they're genetically inferior to mutants.
Charles criticizing the first team for making a party and using their powers for playing, something he was doing in the beginning of the film. They were teenagers who just entered a group where none of them would be considered freaks, what did he expect?!note Charles was drinking in a socially acceptable location, while they had broken all the windows in a government facility.
A more assertive Raven expects Charles to fully accept her mutant form, yet she still insists that he can't read her mind, which clearly indicates that she's not completely comfortable with her adoptive brother's gift.
In The Wolverine, Logan gets really angry at Noburo for cheating on Mariko, his fiancé, despite having slept with her the night before while knowing about her engagement. There's a distinction. From Wolverine's perspective, Noburo, by arranging a marriage with her father, is essentially asking for her hand, where Mariko is being forced to marry him so as not to shame her father. Given his shock when she tells him, it's clear he sees the distinction.
In X-Men: Apocalypse, the title villain despises modern mankind's reliance on technology as he believes it has allowed the "weak" to take over the Earth, to the point that rather than use the world's nuclear arsenal to further his plans, he launches it into space to permanently dispose of it, even remarking on how it was the only thing keeping the modern "superpower" nations in power while doing so. Despite this, Apocalypse himself is reliant on an advanced machine to transfer his consciousness to new hosts and his battlesuit to maintain his current body.
In Logan, Big Bad Zander Rice frames himself as a Well-Intentioned Extremist claiming he didn't want to end mutantkind but control it and prevent random mutantcy so that it went the way of polio. Despite this feigned and pretentious affability Rice still likens mutantcy to a disease, meaning he's not any different from Stryker, Senator Kelly and numerous other tyrannical humans who saw mutantkind as a sickness. Also despite making it his life's goal to prevent mutants from continued existence, Rice himself created mutant children like X-23 by using DNA from natural born mutants, in order use them as weapons.
In X-Men: Dark Phoenix Mystique’s antagonism towards Charles and her big "The Reason You Suck" Speech over his selfishness, just makes Raven look like a hypocrite in light of her actions in the previous films. While Charles is letting his arrogance get to him, Raven is still the last person to call anyone out on being self-centered. In First Class she dumped Charles, her Love Interest Hank and rest of her friends in Cuba all because Magneto found her blue form attractive and spends most of the next movie pursuing her own agenda, ignoring pleas from Charles for her stop and focuses on saving her own skin while Charles and Hank drop everything to protect her from harm. Yet Raven doesn’t acknowledge this during her tirade.
