I mean come on! If anyone can argue that animals are not conscious they are fucking morons or malevolent psychopaths.
At the same time, how can you argue that a consious wolf is somehow in the wrong for hunting and killing the consious rabbit. You can't. Are food chains unethical? What other biological instincts will be deedmed unethical?
