Good lord, people sure are cruel and quick to judge.
I was raised in a very rural area where hunting is so prevalent that we would get the first day of hunting season off of school because people were so inclined to skip that day anyway. The deer population here is so massive that they'd starve if hunters didn't keep the population down.
Now that said, I really hate sport hunting. I find it abhorrent that someone would want to mount an animal's head on their wall, proud that they killed an innocent animal that was defenseless against the power of a gun. I was the weirdo they called the "Bug Girl" as a little kid because I would protect ants from kids trying to step on them.
But for god's sake, I can still recognize the difference between a human life and an animal's. Do I condone his career choice? No. But I also don't know his circumstances, and I also understand through experience with people that hunt that they don't see their actions as inherently malicious, whether I agree with that assessment or not.
Hunting, evening mounting and posing with one's kill, doesn't make him a horrible person who deserved to die and I find the people celebrating a man's death more disgusting than someone who hunts for a living.
