As a consequentialist theory, it is contrasted with nonconsequentialist theories, such as deontology” (Mosser, 2011). The Utilitarian argument of stem cell research is that, although the most valuable research has been derived from aborted human fetuses, stem cell research can cure multiple diseases and greatly advance science and medicine, so this is what should be done. “Deontology is the study of moral obligation and necessity, finding the source of ethical correctness in the rules according to which one acts. It rejects utilizing the results or consequences of an act to evaluate an act as moral and thus is a non-consequentialist theory. It is standardly contrasted with the consequentialist theory of utilitarianism” (Mosser, 2011). Skeptics with a deontological view would counter-argue saying that it is unethical to destroy human life to save human life, so this should not be done. Both of these arguments are complex and need to be evaluated to conclude which has the higher benefit.
Scientists and others who share a utilitarian stance support stem cell research by claiming the ethical cost is low compared to a high benefit. The benefits of
