The movie shows everyone in this society except for the dictator as expendable. That's how dictatorships work. Everyone is relegated to being a product to be consumed and disposed of by Joe. The Wives are simply more precious to him since healthy women (and men) are rare in this world, but should other beautiful girls come along he wouldn't think twice about replacing them. When Splendid is breathing her last breath all Joe cares about is getting his infant son cut out of her.inu-kun said:watched it today, I kinda have to agree there's some sexist shit here, you can't have a film with gender equality while simultaneously playing the "Men is the expendable sex"+"men are all rape monsters and all women are kind motherly christ figures" cards all the time, and there's the "because people like you we are in this situation" line that gets repeated which seems to referring to men rather than anything else. Plus Max is barely a character and no one else gets really expended on so by the end I couldn't really connect to any character to care about what's happening. It's not deal breaking but kinda annoys.
The women (the Wives and the Many Mothers) blaming the men for destroying the world is born out of distrust. This is why they're running away and wanting to live seperate from men. But the movie shows that this isn't the right way to go about it. The final message is one of equality, not just regaring to gender. The movie doesn't end with Furiosa and the Wives going back to the citadel to take over the place and enforce their female law, but with them displaying Joe's corpse infront of everyone and showing they don't need to live under a dictatorship anymore and that everyone can be free.
