The whole thing is the history of betrayal by mutants.

The whole X series is: Magneto's boss wanted to destroy ordinary people, but he and the bald head destroyed it; military scientists made Wolverine, but they were betrayed again; Magneto wanted to turn ordinary people into Mutants, but was destroyed by bald X; The military scientist wanted to destroy Mutant, but then he almost killed his ordinary people, and it was destroyed by the team of bald X. In the end, Magneto just wanted to destroy the vaccine, and was destroyed by Wolverine again.
This whole thing is the history of betrayal within Mutant.
Although the movie reveals the ugliness of human beings everywhere, in the end the biggest winner is human beings.
No matter how sci-fi movies look at humans from the perspective of sci-fi characters, no matter how they speak ill of humans, no matter how "justice" is "maintained" within sci-fi characters, the winner will always be ordinary people. In this way, human beings are always selfish characters for their own sake.
