Kids don't think these days. They act without thinking of the consquences, and such a disreguard of life, they just don't know how precious it is...
They deserve whatever punishment is instore for them. The girl is just as guility as if she threw the punches herself.
Prayers for this young man and family and also the families of the kids that did this horrible thing. I'm sure they never expected this viciousness out of their kid.
