Yes. Every hunter is ethical and will absolutely nail every shot to make sure the animal doesn’t suffer and die a slow death. A hunter missing the killshot and instead wounding the animal? Never happens.
Of course it happens, but for the absolute majority of it's life, even a wounded animal has lived a life in freedom and nature, a proper hunter would absolutely track and deal with a wounded animal to reduce suffering and preserve the meat.
Most people in countries where guns are regulated would not get access to a gun for hunting, mind you. Unless your job is to be a forester, which over here includes selectively shooting animations to balance populations if something goes out of balance.
"I want to get my own deer meat from the forest" is not a valid reason to get a gun. Or even a bow!
You can only get a gun if you are actively in need of one, there are only two legal way to be in need of one, hunting and competition.
You need to get a hunting license from a school, join a hunting society and be an active member to get a permit for gun, or you need to actively compete in a shooting club to get a competition permit. You also need to demonstrate competence and skill before you get a permit regardless of if you are a hunter or a competitor.
Getting a gun for personal safety is not permitted, and to be frank, it isn't really needed here, we have few dangerous animals, and despite the rise of gang violence, Sweden is still a safe country.
Already illegal in most western countries, and I lack enough scientific understanding to judge the feasibility in less developed countries such as many african countries or the US.
