Agreed. I'm not about to defend Benoit here, because there's really nothing to defend, but the people who are using this to point out how much better people they are than others need to get over themselves, on both sides.
I'm not really willing to make the claim that Benoit was "a horrible person" overall based just on this horrific and awful thing he did at the very end of his life. Which certainly does NOT mean I'm willing to say anything good about his character either. I don't know the man, never met him, obviously never will. But this was clearly a man with serious pathological issues and demons, some that might have been related to steroid use, some that might not have been, who knows. I don't know what drove him to kill his wife, though there are any number of reasons why it happens (none of which are justified). As for his son, a man who kills a child, especially his own, with no intention of getting away with it, is clearly a man who has completely lost it and is no longer either sane or capable of normal rational thought. The layover between the death of his wife and the death of his son seems like it indicates that Benoit must have come to some realization of what he had done to his wife and completely broke apart trying to figure out what to do about it. It's not hard for a guy to go from just being enraged or crazy to being completely psychotic with grief and self-loathing at that point.
And he must have been self-loathing since he killed himself. One doesn't do that when they're proud of what they've done. That doesn't exonerate him, though, and if there is another life to look forward to, he is going to pay for it with hell, if you believe such things.
Anyway, that's how I see it, and I don't plan to ponder the murderous actions of Chris Benoit any further. I don't see any point wasting any more time on this man. You can't punish the dead anymore, nor can you undo any of the things they've done, both good and ill. Your thoughts should be with the extended Benoit family and their friends who actually have to keep on living with this tragedy rather than spending your time deciding on "just how evil was this man?"
