Retributivism is a term used to describe the philosophy that seeks to justify punishment based on the idea of retribution or just desserts. Some synonyms for retributivism include "retributive justice," "punitive justice," or simply "justice." Other similar concepts include "vengeance," "payback," or "recompense." However, it is important to note that retributivism is just one way of thinking about punishment, and many alternative theories, such as deterrence or rehabilitation, are advocated by others who believe that the justice system should be focused on preventing crime rather than exacting punishment. Ultimately, the debate over what constitutes just punishment is a complex and ongoing one, and different schools of thought will continue to vie for predominance.
