As cardeer and a few others have said there is legal and ethical and there is illegal but ethical. To me it is an easy one, if the deer is in a real bad way and will not recover, but is suffering, ask the man above what to do, I can tell you what he will tell you, put him down! I will not let an animal suffer! Period!
