Carnivorous animals, are they immoral?
Rape culture among ducks?
Or crows that attack a member of the flock that misbehaved to a minor of the flock? (this is one of the animals that seem to have their own morals).
Anyway: humans should not project our sense of moral to animals.
And humans are no carnivores. Most likely we're omnivores (like our close animal relatives the primates: and they prefer fruit over meat any day, just like human babies).
