people are going to make bad shots no matter how much you practice man and machine is fallible. If it helps think about this man has destroyed most of the natural order of predator vs prey. If someone does not cull the herbivores and other forager type critters they will over populate and eat themselves into starvation. Also how many animals get hit by cars poisoned or otherwise harmed by unwitting uneducated people. Sometimes the natural or in our case unnatural order (humans replacing natural predators) is very raw and cold. Just do the best ya can make sure you do everything in your power to locate the injured animal and end its suffering.
