Injustice is a quality relating to unfairness or undeserved outcomes. It can refer to a particular event or situation, or to a larger status quo. In Western philosophy and jurisprudence, injustice is commonly defined as either the absence or the opposite of justice. Injustice can be caused by human action such as misuse, abuse, neglect, or malfeasance that is uncorrected or else sanctioned by a legal system or fellow human beings. The sense of injustice is a universal human feature, though the exact circumstances considered unjust can vary from culture to culture. Injustice can be a powerful motivational condition, causing people to take action not just to defend themselves but also others who they perceive to be unfairly treated. Examples of injustice include economic injustice, violation of the rights of others, and unfair action or treatment.
