In children's cartoons, there's inevitably the line that even the comic villain won't cross. You'll have Skeletor punch three guys in a row and then step up to a baby, hesitate, turn to the camera and say "Well, I'm not a monster" and walk past.

Then you've got IRL IDF who straight up do long-form prose explaining why they were fully justified in dropping artillery on a daycare.

Fiction has to make sense. But reality gives storytelling the middle finger and it does whatever it wants.
