Alot of the wrestlers seem to 'go off the rails' to some extent, like alot of celebrity type figures do. I liked Benoit as a wrestler, although I haven't watched it since I was in primary school (probably about year 5/6/7 to you lot). You tend to get more easily angered just watching wrestling, imagine if you actually took part in it? I remember seeing on some program about Hogan and his family (my sister's choice...she guards the TV remote with her life) that he was having stuff injected into his spine so he could keep wrestling...again if your body is that knackered, surley you'd think that retiring might be an idea?
As for what Benoit has done, even given the above, they can say what they like about steroids, pressure etc, but there's still no excuse. That's insanity, and he shouldn't have been allowed anywhere near his family in that state. Imagine what that will feel like for his relatives, the shock of one of their family doing something like that?
