This is the natural world. Animals and people die. Country people love wildlife too. They just don't delight in seeing them standing on the side of the road. When they do see one, they grit their teeth and prepare to take evasive action.
When deer numbers are too high, you are likely to have one come crashing through the windshield. Discussing the situation doesn't make us any less civilized. Even the jokes are normal behavior.
Besides, everyone should have to kill their own meat at least once in a lifetime in order to gain a greater appreciation of it, and what it represents.
