>No. A normal kid wouldn't throw rocks at buildings. It is just instinct. So there are natural instincts that prevent kids from throwing rocks at cars, hospitals or power stations.

Natural instinct? No, it's upbringing.

And a lot of kids have shitty upbringing. It doesn't even have to be of the "father was an alcoholic, beat mother etc" kind. It can be "I had a perfectly good family that bend over backwards to satisfy my ego" type, or "I got most of my intra-personal skills off of TV and the internet", type.
