Is a game worth killing someone?

I was watching a show on National Geographic last night and it was on Football Factories. I was scanning through the channels and came across this show. I was surprised to see fans of football (soccer) who were in such a frenzied state that it was hard to believe they were watching something they enjoyed.There was such violence that I would be afraid to attend a game and cetainly would not suggest taking a child to one.People were being beaten wih sticks and being kicked while they were on the ground,defenceless in a fetal position.I listened while the announcer was talking how somw of these spectacles resulted in deaths.It appears that some of the"devoted fans" called it pion for the game. All I could think of that was someones son or daughter, husband or wife being beaten to death.We tell our children to be good sports .What does this behaviour teach our children about being good sports?I just don't understand this.Can someone please tell me when the love of the game was lost.
