the terrible question

Why???
Sometimes we just do not want to answer this question because....maybe we can't, maybe we don't want to..maybe we don't know. I sit here, thinking of the news I read the other day about how a father killed his 3 and 1 year old kids and then hung himself...What in the world??? WHY? How is it possible for a parent to kill his or her own flesh and blood. It is not only heinous, but mind boggling. Even our natural instincts is to protect our young, so how can people do the very extreme opposite? My only answer( if there could ever be any) is that the person must have been deranged. Flat out of his mind and no longer thinking rationally. But the worst possible thing must have to assign the blame on his wife by leaving a note saying he had to do it out of domestic troubles. Even to the end he refused to see his part in it.
I am married. Maybe not for a whole long while ( 4 years) but I do have kids and I do have husband who, shall I put it mildly, at one time or the other has had altercations with me. I know how it can get...Although I hasten to add , I do not know the background of this particular couple in the news piece, only that they were estranged. The children were living with his wife at the in laws house. He had picked them up, brought them to his house before committing the horrible acts of putting weedkiller in their milk and then hanging himself.
What could have been going through his mind as he went through these motions? Was it the possibility that his wife would no longer let him see his kids? Was it why he did what he did? In moments were we are feeling emotionally hijacked ( to borrow a term from Goleman) maybe he just didn't see any other way of dealing with the situation. I feel sorrow for the kids, the family, and the man himself for having condemned himself and his kids to such a fate. Maybe the lesson to be learned here is that in moments of crisis, remember to reach out for help. You are not as alone as you think.
