...&quot;go to jail just because society does not know what else to do with you...&quot;<p>The purpose of putting to people in jail stems from the 3 Rs: Retribution, Removal, and Rehabilitation. Retribution: punishment for the crime. Removal: removal from society so no further harm can be committed by the individual. Rehabilitation: make the individual a better person so they don&#x27;t commit more crimes and become better citizens.<p>Unfortunately, we usually don&#x27;t accomplish all 3, but 1 of the 3 usually gets done.
