 Utilitarians will object that this second solution provides too indirect an account of what ultimately grounds our obligations to animals. The fact that it is wrong to inflict unnecessary pain on animals is not most plausibly explained via the notion of whether this behaviour could be justified to a trustee of the animals. Rather, it is wrong simply because of the suffering the animal feels. A utilitarian will add that, once we realise that this is what is wrong in the case of animal suffering, we should draw the same conclusion about human suffering. It is their capacity for suffering rather than their capacity for rational agency that plays the most salient role in explaining the wrongness of torturing humans.
