lol at the above post.
This just seems like a schoolyard fight that got way out of control, but really, when I went to school there was a fight after school like every other month or so, and this has been going on with kids since forever.
The fact is the human brain doesn't fully develop until into its 20s ... kids don't always understand the consequences of what they're doing and can be cruel. That's just a fact of life, you're never going to create some utopia where kids don't get into brawls.
Most boys at least get into at least one physical fight in their childhood.
