There's no place for "ethics" in hunting feral hogs/sus scrofa -- NOT to be confused with European wild boar or Russian boar. Feral hogs in the US and Australia are a non-indigenous species and a man-made pest. Ethics left the station back when idiot livestock growers free-ranged hogs and inconsiderate "canned hunt" outfits transported and set them loose. They breed faster than any other ungulate, compete with indigenous wildlife for habitat, spread disease to other animals, and destroy property. It's pest elimination, no different than swatting flies or killing cockroaches.
