Is the point of prisons to restrict freedom as punishment for crimes committed? Should prisons be rehabilitative? Are prisoners supposed to emerge from the experience deterred from committing future crimes and morphed into law-abiding citizens?
The purpose of prison is retribution
Prison should be an unpleasant experience to ensure the criminal pays for the harm they have caused.
Prison means justice for victims
Criminal activity violates the social contract and harms one or more victims. We must hold people accountable for these actions.
