Killing the wolf saved both the children of busy parents that couldn't be bothered to break their legs, and the children that grew old enough to have their leg fixed but weren't yet adult.
Today instead of chasing predators away from children spaces, we just box the children so at one magic birthday they'd be out in the world untouched by evil. The world will be still evil however, and the not children for a day unprepared for it.
What if, here's a radical idea, we terminate corporation with toxic ads or that let predators use their system to target children.
