Its so much more than just 'killing'. Nobody would enjoy euthanizing a injured farm animal or something like that. I enjoy stalking, the field craft, the skill of making a good shot, and enjoy looking at a wild animal, being able to seeing its beauty up close. Taking it home and eating it. Shooting is great fun! No need to feel guilty.
If you eat meat do you feel guilty for enjoying a burger? Because you helped kill that animal.
