Um, the English and American justice system and sending people to prison had 5 main motivators. Deterence(to motivate both the person and everyone else to not do the act), reparation(repair the damage the person did to society), rehabilitation(correct the behavior), incapacitation(prevent the person from continuing their actions even if only for awhile), and retribution(pure revenge). Even though the corrections system has shifted a bit towards rehabilitation the last decades, retribution is still a very powerful motivator. However, the difference between the retribution the state inflicts and the one I was hinting at are different because the state inflicts retribution by stripping people of their freedoms and caging them up. Mine was corporal(sp?) retribution.
