Autonomy, the first of the four fundamental principles, is to respect others' choices and human dignity, while beneficence is to bring about good in all actions. Justice is the obligation to treat others fairly, and nonmaleficence is to cause no harm or the least amount of harm possible.

Deontology, one of the five major ethical theories, is to adhere to duties and obligations in an ethical dilemma, while utilitarianism is choosing the action which provides the greatest benefit to the majority of people.
