Its not about the
prey species' sentience as much as its about me being a carnivore.
I do not think a Lion or a Tiger is evil, or doing anything wrong when it eats a deer or a farmer.
They are carnivorous, and evolved to eat meat.
If PETA, etc, wants the carnivores all killed to avoid them eating prey, it would make just as much sense.
Why say that one species, say, Tigers, are no longer allowed to eat meat, because its unfair and cruel to their prey?
What about Chimpanzees and Baboons, etc? They eat meat...Should we make them eat only plant matter?
Humans? Should we ONLY try to change what humans eat? Is there some reason that its OK for a Zebra to be torn apart by a pride of lions, but not ok for a human to whack a chicken?
Why are they prejudiced about humans?
Is it just because we can THINK about that zebra, and decide that maybe we feel bad for it...and go have a banana instead?
So, if a lion is not ABLE TO THINK about the zebra, other than as a striped bag of meat, perhaps the lion is not sentient in a way that we hold ourselves to.
So, if we EAT a lion, we are therefore not eating a sentient being.
If we DO consider the lion to be sentient, then we consider it to be evil, as it chooses its own welfare over the zebra's,and would murder the zebra for the sake of a meal.
So, if the lion is murdering the zebra for a meal, then we are murdering a chicken for a meal (OK, we mostly hire a hitman, etc...).
If its wrong for the lion, then its wrong for us.
If its ok for the lion, then its ok for us.
