Answer:
Good and Evil
Explanation:
Ethics or moral philosophy is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct. The field of ethics, along with aesthetics, concerns matters of value, and thus comprises the branch of philosophy called axiology.
The three schools are virtue ethics, consequentialist ethics, and deontological or duty-based ethics. Each approach provides a different way to understand ethics.
The principles are beneficence, non-maleficence, autonomy, justice; truth-telling and promise-keeping.
