There are many ways to " respect" an animal, IMO. One way is taking ethical shots, and making sure that your kills are quick and humane. As far as mounting the deer or not, it is up to the hunter that harvests the game. It is his decision and nobody elses. I myself would mount a deer if I harvested a big buck. I may respect the deer in this way, while other may respect the deer by putting just the antlers on the wall. I believe the only way to truly respect the animal though, is to waste no parts, and to not kill more than is necessary for you. Respect the animal, and respect the fact that it give it' s life so that you can survive.
