In life it is always easier to blame what you don't understand.
Gang violence is alot of the time blamed on rap music and weed, which is a joke, who the hell goes out and gang bangs because of a song? Do you see people going out and getting into bar fights because of a song Toby Keith might have written, or do you see someone becoming so infatuated with a boyfriend/girlfriend cheating that they go out and demo that persons truck as Carrie Underwood says in her song....NO.
It is the person and what is in there head and the emotions they have inside them. No drug such as AAS will make you have roid rage, to the point of killing someone, sure it might make you get more upset or curse and yell at someone, but it will never make you get to the point of killing them, not to say it has never happened, it's just something I've never heard of. I've never been to the point of wanting to harm someone to that point of death and I've been on it for 15 years.
As far as Meth or crack or Coke, ya I could probably see it putting you in a sense of higher state of consiousness, hence the reason people kill themselves on it as they think they are above death. Or killing someone as the reality of the situation may not be there to them at that point.
I can speak from past experiance as I have met Chris a couple of times at shows and such back in the day of the Calgary Stampede. He was always very quiet, but very intense about his job, he reminded me alot of Val Kilmer and how he is a perfectionist. He loved the buisness and what he did. As far as the comment about Eddie Gurrero, I would only assume that he took it hard as it was his best friend and he was like a brother to him. But Rey Mysterio was just as close, and this hasn't affected him like this.
Bottom line is you are your own person and only Chris will know what pushed him to this state and what caused him to do what he has done. I don't agree with it nor do I condone it...but it's happened and that's something that all of us will have to deal with...friends, family and fans alike.
R.I.P Chris as you will missed by wrestling fans everywhere and thank you for the memories of all the famous matches you wrestled, the man help put wrestling on the map in Canada.
