I think the whole hang up is the relation between man and dog and the wolf being so closely related and resembling a dog. If you get past that and just generalize it as another big game animal that is a predator, much like a bear, it makes perfect sense to eat it. Meat is meat as long is it is a healthy animal and it's diet is a quality one why not?
Exactly why I am going to wait 10 minutes before walking up on the next (2nd) wolf I shoot. The gurgling and twitching, and "green fire dying in it's eyes" kinda got to me on the first one. Too much doggish, and I've killed several of those, including one of my own Labs. No longer bothers me that much on herbivores... a finishing shot to the base of the head pretty much ends it all right there.
