Moral life often presents us with trade-offs between the sufferings of some individuals and the sufferings of others. Researchers may need to consider, for example, whether the suffering imposed on animals by a certain line of medical experimentation justifies the relief that the resulting discoveries may bring to (human or non-human) others. Often in such cases, the suffering of some individuals is incomparable with—that is neither greater than nor less than nor equal to—the suffering of others. While this complicates moral decision-making across species, it does not undermine it.
