Not at all. If there are no predators to keep a population down, then hunters can serve that function. Its neither Christians nor the National Geographic that monitor these populations, its the DNR. Its more humane than allowing mass starvations.
As far as your "shepheards of the flock" comment, consider the Native Americans. The Sioux had short bows with limited range, but they were great hunters because they were great trackers. They acclamated themselves with wildlife and killed only what they needed to survive. Hunting isn't senseless killing.
Maybe the "mass starvation" in Darfur can be remedied by benevolent hunters? Wouldn't that be "humane"?
Today, in America, hunting is pointless, immoral, and criminal, from factory slaughtering of animals to idiotic game hunting. The advances in technology can create nutritious, delicious food without murdering animals any longer. Yet they don't, and their justifications are absurd. Just because the state of things is absurd, I'm not going to argue that it is in the least bit reasonable.
Besides, guns don't kill people....REALLY FAST bullets do.
Guns don't kill people, rappers do.
I'm a rapper and I might kill you.
Sound of the police - woo - woo - woo.
