It is normal for animals who don't think the same way that we do. They don't understand the concepts of "killing" or "life" and don't value life in the same manner as humans.
It's always struck me as odd when unethical treatment of animals is justified by saying "animals eat/kill/hurt other animals too!". We're different from animals. Our standards should be higher.
Many animals do understand killing and death. Elephants are a prime example of this.
Also, what is unethical about eating an animal? If this is really an issue, then we should be out there killing all those murdering predators like wolves, right?
Setting aside the obvious questions about how wild vs farmed animals are raised, wolves don't have a choice about what to eat, while humans do. Even if we wanted to improve the status of wild animals, murdering wolves isn't obviously the best way.
So what if they don't have choice? If a mentally deranged person commits a crime because they didn't have a choice, we still remove them from doing further harm from others. Would you not kill a wolf attacking a person? If we are saying that animals are equal, then we should also be protecting the innocent prey.
Right, but you're trying to justify your actions by bringing up the actions of the mentally deranged, as if that somehow absolves you of responsibility.
