What's the appeal of eating mammals?

When I see OP image I don't think "food". It just looks like violence and death. And where's the food value? That thing probably has zero fat, just lean muscle meat. Plus you have to do a whole bunch of processing and cooking and seasoning and aging just to swallow it.

My body has no natural reaction of "food, eat" when seeing dead mammals.

When I see fruit my body knows it's food, when I see vegetables my body knows it's food, and same with legumes, and to a certain degree, lettuce. But not mammals.
