I'm sure most understand that killing the deer isn't the cruel part. Most on this site fully understand that killing the deer is necessary, if the goal is to get to the backstraps. Having the deer carry around at least 4 times the amount of mass and weight on its head with its neck that couldn't possibly be suited for such a job, strictly because some moron wants to see how big a set of antlers can get, is the cruel part. Just like the guy in Wyoming, killing the wolf wasn't the cruel part. Running over the wolf first with his snowmobile and parading the animal through the bar before putting it out of its misery, was the cruel part. Some find it fine to treat another living and breathing being like its only purpose on earth is their utter enjoyment or intrigue.
I'm not trying to tell you that animals have feelings too but I can only assume they feel pain like humans do. Pretty sure I've had a buck or two tell me it hurt when my shot wasn't spot on. I've branded and dehorned a few calves. I've cut my dogs nails too short and once pulled his punctured, bloody jowel off of his canine while he was screaming quite loudly, "hey that friggin hurts."
The cruel part is watching a living breathing animal be miserable and suffer for ones own entertainment.
I didn't open the link because I saw the article somewhere else and thought to myself then, hunters are their own worst enemies and maybe when we as a collective, lose our rights to hunt, there may be a few of us that deserves it.
