That's silly thinking. Then just give them one cartridge. Better yet - teach them proper gun handling safety. Your dad's experience is very anomalous.
I thought the same and didn't say it. My dad tried to calm down my passion for firearms when I was a kid. It didn't go as planned as my mian passion is... Teach your kids with firearms young, explain it well to them and they'll learn. A semi isn't rocket science by any means.
There is a lot of video on youtube of kids as young as 10 shooting 9mm pistols. Don't be overprotective, ask them what they have to do to be safe with a firearm EVERY single time untill you can decide they are GTG. You always need to act like a firearm safety instructor until they can legally have their own. My friend has kids and I shoot guns with his kids while he's doing other stuff on his property because he knows that I know my guns and how to be safe with them.
