The real issue here may turn out to be steroids. If, as has been reported, there is a link between Benoit's bizarre behavior and steroids (say, for example, his suicide note bemoans the effects steroids have had on his body and mind, or he left syringes of steroids scattered about), the WWE will be in real trouble.
I mean, for the first time, Vince will have to admit that 'roids is a real problem and has led to the deaths of multiple wrestlers (can anyone deny that?). I'm not sure the WWE would recover, frankly.
