"The death of a gazelle after painful torture is just as bad for the gazelle when torture is inflicted by a tiger as when it is done by a human being. That does not mean that death by tiger is as blameworthy; obviously it is not. But it does suggest that we have similar reasons to prevent it, if we can do so without doing greater harms. The capabilities approach is entitlement-based and outcome-oriented. One way of preventing gruesome deaths of animals at the hands of other animals is to put all vulnerable animals (or, alternatively, all predators) in protective detention, so to speak."
