It is ethics with respect to real-world actions and their moral considerations in private and public life, the professions, health, technology, law, and leadership.
[1] For example, bioethics is concerned with identifying the best approach to moral issues in the life sciences, such as euthanasia, the allocation of scarce health resources, or the use of human embryos in research.

Casuists, like Albert Jonsen and Stephen Toulmin (The Abuse of Casuistry, 1988), challenge the traditional paradigm of applied ethics.
Thus, a Rabbi, a Catholic priest, and an agnostic might agree that, in this particular case, the best approach is to withhold extraordinary medical care, while disagreeing on the reasons that support their individual positions.
