Just replying to one point in general here: Animals have a wide range of emotion. If they had no sense of mortality they would not show fear of predators or lightning or unpleasant humans getting close to their coop. But they defend themselves as best they can. They defend their families with all they have.You realize animals have NO sense of mortality, right? All they know is if they're content or suffering. By allowing an animal to suffer because YOU fear death is a sin so vile I can't believe you'd even defend it.
I believe however one cares for them, whether as economic units that are owned and subject only to one’s ideas, or as sentient beings with their own journey, will stay with you for a very long time since it is your own mind that creates these concepts of value along with whatever cultural momentum is streaming at the time.
