Final answer:
Punishing prisoners for the sake of retribution does not justify different treatment under modern correctional philosophies, which value security, ethical treatment, and rehabilitation.
Step-by-step explanation:
Under the new philosophy of prisoners' rights, c) punishing prisoners does not justify a different treatment of prisoners. The focus is on maintaining internal order and discipline, securing the institution against unauthorized access or escape, and rehabilitating prisoners. Punishment solely for the sake of retribution is not a primary objective and, as such, does not serve as a justification for disparate treatment under modern correctional philosophies. The current justice system aims to balance security with ethical treatment and reintegration into society.
