If we're assuming he didn't kill everyone but everything else stayed the same, the chances are he would have been released eventually and recommended to be put into some sort of care. If we're totally ignoring the whole brain damage thing, he'd have helped get people over in ECW for a while, most notably Punk and then probably John Morrison too, before either retiring or gradually reducing his role to a Goldust style one. He would never have won another world title, and I doubt he'd be wrestling at any sort of elevated level by now.
To be honest, Benoit's injuries are pretty remniscent of someone who takes the industry too seriously and makes too many sacrifices, so if he hadn't have ended up with brain damage, I imagine he'd have wrestled till he was incapacitated somewhere, probably ROH or somewhere like that.
