People really, truly need to learn the difference between protagonists, antagonists, heroes, and villains, and where the line between them is. A protagonist is a character who the story centers on, while an antagonist is a character who opposes the protagonist; a hero is a character who is doing the right thing, while a villain is a character who is doing the wrong thing. Not all protagonists are heroes and not all antagonists are villains.
Superman is a hero protagonist, and Lex Luthor is a villain antagonist. LISA: The Painful has Brad as a villainous protagonist and Rando as a heroic antagonist (though you don't learn this until later on). Megamind is a villainous protagonist for most of the movie who becomes a heroic protagonist in the process of fighting a villainous antagonist (Titan) who he created to be a heroic antagonist. Breaking Bad features Walter White as a villainous protagonist who often fights against Gustavo Fring, a villainous antagonist. Across the Spider-Verse features a hero protagonist clashing with a hero antagonist over conflicting views of what is right and what is necessary. Terry Pratchett novels have an overabundance of characters who fall on every single side of the morality divide and many who fall between it.
Stories are not always about good people fighting bad people. There can be so much nuance when it comes to a narrative, and reducing it to... to superhero vs supervillain fistfights is awful! There is a place for such narratives, but not all stories need to be that- not all stories should be that. Stories about villains trying their best for their own reasons, about heroes who can't agree, about shades of gray where no one is in the right, about a world where the heroes simply aren't enough and other villains have to step up... these concepts can be so interesting if you just bother to read them and think about it instead of blindly insisting that a protagonist is always good and an antagonist is always evil.
In short: expand your horizons, think critically about what you watch and play and read, and understand that real-life villains never see themselves as villains.
