I still can not grasp the concept

Just a sounding board, need to just speak.....I was not sure if I wanted to post for a few days until my shock and anger passed, but I decided I would Blog anyways. I got a couple of phone calls yesterday that a wrestler Chris Benoit, his wife Nancy, and their son Daniel were found murdered in their home. I was not personally effected, but still very upset I have met both Chris and Nancy in the past many years ago. I followed Chris's career as I thought he was this hot blue eyed fantastic wrestler (besides he wrestled with local outstanding wrestler Dean Malenko), I cried almost all night watching the TV as WWE did a 3 hour tribute showing some of matches along his years of wrestling (including some from when he was here and ref'd by a good friend), and some of his friends and co-workers commenting on him - how he was such a loving father and a great respected man. I did not want to even think that Chris did it, all kinds of news were pouring in, one time they even said that when he called into work to say he would not be there for the matches - was because Nancy and Daniel were coughing up blood (I am thinking and hoping it was posions in the home). As the news continued to pour in, it has now been reveiled that he did kill Nancy on Friday, Daniel sometime Saturday, and then himself on Sunday. I still can not grasp the concept, what would trigger him to kill her on Friday staying in the home with his son about a day before killing his son, and then the next day himself? There are some very deep sick angry people in this world that you have no clue of what they are able to do. It is not like he was a washed-up has-been of a wrestler, he was scheduled for a house show Saturday, and the PPV on Sunday. He called on Friday to say he would be delayed and taking a later flight, Nancy was either already dead, or about to be killed. Did Daniel know his mother was bound and strangled in the other room, or did he know nothing and was murdered in his sleep. I am hoping for the lessor of both evils and that he did not know, and he was murdered in his sleep. It is pathic it happened at all, but to know your daddy just killed your mommy and she is laying dead in the other room? It just sickens me to no end! I am still in such shock over it. John Winter having an affair and could not cope kills himself - but to kill your 7 year old child? A temper is one thing, but come on?
