Do they? It’s city dwellers who never seen prey and feel guilt. Regular hunters just skin the carcass and think where to store it. Guilt is a social emotion that leaks into areas which are not clearly separated in an experiencing mind.

> do they? Yes, it's plainly obvious that some people feel some guilt for eating meat.

Regular hunters != industrial-level slaughtering. There are plenty of "regular hunters" who only eat meat they kill themselves. This is like saying if I cut down a single tree on my property I should also support the clear-cutting of the rainforest.

Rainforest is not a good analogy, imo. It presumably is an important part of an ecosystem and also sort of a nature’s museum. Farm animals are absolutely synthetic and barely play any positive role in ecology. So if you cut a single farm animal, I don’t see why 8 billion others shouldn’t do that or should feel bad doing it.

All that said believing no animals should get slaughtered. If we do it to some, could as well do to many. See https://news.ycombinator.com/item?id=42642138 tld: I don’t believe in reducing numbers, because the reduced numbers mean nothing to the animal being slaughtered.

To prevent over-hunting to the point that prey becomes extinct? I'm not having a hard time imagining how shame could be an evolutionary advantage.
