It’s weird to be cool with violence and be bothered by nudity…in general. Context matters, see my complaints about Blade Runner 2049. In a vacuum I think violence is much more problematic, but nothing exists in a vacuum other than dirt and a bunch of dog fur.
Violence doesn’t cause sexual temptation (usually), which nudity might. That’s the bigger issue for Christian viewers.
Christians should be able to control themselves but what do I know.
I don’t see boobs and immediately have sexual desire and start doing my taxes.
I will say that it has happened though.
