If I jumped out of an airplane without knowing the proper way to open my chute, and ended up dying - would you say that I was still a good kid, or would you say that I was a fucking moron for putting myself at risk without having the proper training to prevent me from getting hurt?
That being said, it's always a shame when someone gets hurt in a wrestling ring. The first thing that you learn in training is that you have to protect yourself, and the person you are working with at all times in there.
