Ethics is the study of right and wrong, good and bad. Ethics is often split into two parts: normative ethics and meta-ethics. Normative ethics is about trying to figure out which acts are right and which wrong, and which states of affairs are good and which bad, and who is a hero and who a villain. Meta-ethics is about trying to figure out what is means to call an action ‘right’ or ‘wrong’, a state of affairs ‘good’ or ‘bad’, or a person a ‘hero’ or a ‘villain’.
