Please watch this video called "Ethical" Hunter says "let the deer lay up and die".
One only has to visit "tracking wounded deer" sites and the advice that are given to other hunters, by hunters to realize how much they could give a damn about the suffering of our animals. They want you to wait till you start retrieving the deer because the deer will still be alive and very much suffering but they want the animal to die by the wounds so they do not push the deer to run any further. There is hardly any talk of mercy killing.
Whether deer run off and left wounded to die without being found or wildlife killers just waiting for the animals to die both ways is so horribly cruel and unnecessary pain and suffering.
