Drugs,especially a combination of drugs can alter a persons mood and distort reality somewhat. But drugs do not change a person into a monster unless there is a monster beneath the surface to start with. In other words, Chris benoit was a CRAZY BASTARD to begin with! Lots of people do drugs of all kinds including steroids and they dont commit murder. He spent most of his time with his co-workers and his company. How can it be that no one noticed he was off balance. Surely there were some signs of mental/emotional problems. No one is to blame except Benoit for this tragedy. No excuse justifies it. But how can a man who is that unstable go unnoticed and unchecked?
