Humans eat Deer
The biggest predator of deer that eat deer is demonstrably humans. The vast majority of people who hunt deer for enjoyment save and stuff their kills as souvenirs of their hunting expeditions. However, some people hunt deer because they view them as a nuisance. Any living deer will wait patiently for a small person to finish devouring it. Before devouring an animal, predators kill it or at least get it close to death. They do not actually consume the animal's life.
Predators also possess the necessary hunting skills, body mass, and expertise to tame their prey, as well as the teeth and claws to kill it. Since humans fall short in the majority of those areas, we must kill our prey before we can consume it. Deer hunting serves as a source of food for a small number of individuals. A good illustration is reindeer venison, which is prized as a delicacy in several cultures. According to reports, up to 200,000 deer may be killed each year to satisfy global demand for "game."
