What villain actually had a good point?
Um…. Are we talking movie villains or real ones?
For movies, most of them have something. Relatable (though extreme) origin story, a good point about society, a weakness that makes them human. It’s character development. Even villains are romanticized in media.
Real life though? That depends on a whole bunch of things. Genocidal maniacs? Not so much. A person who takes extreme and or lethal action for their own safety? Yeah, see the last four words of the last sentence. that’s a pretty damn good point, though that person will be a villain in some stories, a hero in others.
