I think Perna is mostly right but I can't help thinking that all the violence on TV and games contributes a lot to that way of thinking.

I've got two 8 yr old granchildren, cousins, one a boy and the other a girl. Either one of them would run home to mom and dad scared out of their wits if their classmates were planning such a thing! The boy is Aspergers but that wouldn't matter. He's Special Needs but much has to do with what they are allowed to do or not do at home.

The girl is learning to use a 22 rifle but there's no way she'd even at aim at something she wasn't going to eat! Her five yr old brother has sworn off killing ANYTHING that's alive. He wouldn't even kill one stinkin' snail in his collection while they were here last week.
