Super nice! You'll have to tell your buddy congrats!
77horses, are you a vegetarian/vegan? If you do eat meat, you know it obviously comes from somewhere. Sure, it's sad to have to take the life of an animal, but at the same time, as long as the meat doesn't go to waste, it isn't really a complete loss. Of course, this depends on your philosophy about the food chain, which for some people, has to do with religion, so probably doesn't need to be discussed in depth here.
At the least, I don't doubt the person who shot this buck plans to take it in and get it butchered. It will feed his family for a long time. People who say the buck looks delicious are just remembering similar experiences eating venison. In a thread about a hunting accomplishment, you're probably going to see a lot of positive comments in response to the original post. You, although you have a right to your personal opinion, came across as somewhat condemning.
