On the other hand, while Kant accepts killing animals—perhaps thinking of our food, although he doesn't explicitly say so—he imposes two very "human" restrictions: their death must be quick and painless (90). In this sense, our author would condemn the deplorable conditions in which animals are kept today on factory farms and the way they die to satisfy the market demand for meat. Kant would even oppose the slaughter of animals to please carnivorous humans, since, as we have already seen, no human desire justifies animal suffering. For this reason, we agree with Matthew Altman when he states that the ultimate consequence of Kant's stance against the cruel death of animals would be to adopt a vegetarian diet (91).
