Deontology is defined as an ethical theory that the morality of an action should be based on whether that action itself is right or wrong under a series of rules, rather than based on the consequences of the action.
Deontology (or Deontological Ethics) is an approach to Ethics that focuses on the rightness or wrongness of actions themselves, as opposed to the rightness or wrongness of the consequences of those actions (Consequentialism) or to the character and habits of the actor (Virtue Ethics).
