Same with action movies - main character does a lot of damage to everyone around, steal cars, hurt innocent people and we are supposed to ignore that. Happy end involves massive fight in the middle of city that would displace thousands of families. And so on and so forth.
People take the usual expected reading of movies and apply them to these too.
It is possible to make movies differently. I have seen movies that made me feel bad about violence and events and that made it clear that "this is not a cool thing". But the movies mentioned here are not like that - they sort of criticise it but are still made so that we feel happy about them. They show events from the point of view of perpetrator, but not much from point of view of their victims.
