I suspect Red and I live a couple hours apart. Here are my feelings:
(1) There are many deer around here, so it may be different than where theashleys lives in Australia -- I doubt this will impact the deer population is any substantial way. Certainly not if it's only done for food for a family that's going hungry.
(2) You need to provide for your family. Hard times mean hard choices. It's ok, if you're out in the woods, because you have to do it to feed your family. Just like I think it would be fine to steal a loaf of bread to feed your children if you're homeless and have no other choice.
(3) It is never ok to shoot animals near where people live, on private or public property. There are laws addressing this outside of the poaching factor. It's just not safe, and a lot of people are accidently shot.
(4) Any other reason -- totally unacceptable.
