Ethics or moral philosophy is a branch of philosophy that involves questions about morality and the perception of good and evil, of right and wrong, of justice, virtue, and vice. It has the following branches: meta-ethics, normative ethics, applied ethics, moral psychology, and descriptive ethics.

These branches have several different schools of thought and subfields, among them are: hedonism, Epicureanism, stoicism, modern ethics, applied ethics, moral psychology, deontology, and teleology or consequentialism.
Deontology is also referred to as duty-based ethics. It is an approach to ethics that addresses whether the motives behind certain actions are right or wrong instead of focusing on whether the results of the action are right or wrong. It is based on each individual’s duty or obligation towards each other, all living things, and the environment based on moral beliefs and values. It teaches about always acting in good faith and adheres to the Golden Rule to treat others the way you want to be treated by them.
