The comment you link to does do a better job of explaining what you’re getting at, but I would still argue that those behaviors also require a partitioning of empathy, and that is a behavior most humans are susceptible to… Those who have empathy can often be made to shut it down or partition it so that it only applies to certain people.
I stand by my original comment modulo the part that asserts that it is empathy. It is not a lack of intelligence being the point.
Yes, but the point about minimizing plant deaths by eating plants instead of feeding more plants to animals and then eating the animals is a valid one…
