Other animals eat each other. Why can’t we eat them?

Predators in the wild kill other animals out of necessity.

Without doing so, they would not survive. Humans kill other animals by choice. Our bodies have no need for meat at all. In fact, it has consistently been shown that a low-fat vegan diet is healthier than a diet heavy with animal products. Is it acceptable to inflict suffering and death on countless animals for something that isn’t even necessary but simply a dietary preference?
