Look you now, I’m getting very angry at all these people who seem to feel that someone who expresses sadness and anger over the death of an animal is somehow immune to the deaths of fellow humans. I agree with Poysyn’s sentiments- sometimes the most unexpected grief comes from the most unlikely source. And I agree with Guinastasia- the death by torture of an animal is compared by many, myself incuded, with the death by torture of a human child- both represent innocence and dependency that fellow adult humans do not, and the death of one of these is sometimes more heart-rending and rage-inducing.
Millions of animals are in fact killed in the US every year, often in horrifying ways, in biomedical research facilities, in industrial trials, and in shelters. Some say these deaths are justified, that they serve the greater good. Some disagree, and would argue we have no right to use our fellow creatures for our own ends. I agree that you cannot point any fingers at any other society for their use of animals- we in the US do the same, though we would like to think we don’t, and do our best to hide this unpleasant business from the public eye.
To me, any needless death is a tragedy, be it human or otherwise. Life is life, precious in any form it takes, and not to be disregarded or used lightly. All pain and suffering, of any living thing, causes me grief. The sense of irretrievable loss and sorrow I feel is the same at any death, for a human or a dog. Every death is to be mourned.
All this said, I do have to wonder- how can anyone be surprised at anything Al-Qaeda does? They have already proved themselves to be utterly disrespectful of life, even of their own. They have consistently shown a contempt for the lives of all things, and they are bent only on destruction. No action or word of theirs will ever surprise me again. Sadden me, enrage me, but never surprise. They are capable of anything, and will not shrink from any deed, no matter how odious or contemptible.
Somewhat off-topic: although I added shelters to my above list of places in which animals are routinely killed in numbingly large numbers, I feel you cannot really place any blame on shelter workers for the euthanasia of animals. It is in my mind akin to blaming the undertaker for the ravages of a plague- he is only cleaning up the mess. True fault lies with those who abandon their pets, who do not spay or neuter, and those who otherwise behave in an irresponsible and reprehensible manner towards another creature whose well-being they disregard, through cruelty, selfishness, or ignorance.
