A government statistical study once showed kids raised with guns and who'd been given guns by their parents were much less likely to do drugs or commit gun crimes.
Responsibility is something that grows with proper supervision interaction.
Years before that study was written, I was visiting my grandmother's farm as a boy of about nine or ten, and I saw a several boys walking down the dirt road with rifles over their shoulders. "You can tell those are good boys," grandma said. "Otherwise, their parents wouldn't have given them those guns."
