Depends upon how you construe the word "prison." If it means prisons of the sort most common today (i.e., in the US), then the answer is No. If you mean a place where dangerous criminals can be separated from the rest of the population, then the answer is Yes.
There are two contending models for so-called "criminal justice systems": the punishment model and the rehabilitation model. The first assumes the purpose of the system is punishing offenders, per the theory that attaching unpleasant consequences to criminal behavior will deter that behavior. This approach also resonates with the Old Testament concept of justice, i.e., "an eye for an eye." The rehabilitation model contends that the purpose of prisons (and the criminal justice system generally) should be rehabilitating the offender --- identifying whatever personal experiences or difficulties or lacks "caused" him to commit the crime and providing him with the counseling, training, and other support he may need to overcome those lacks.
Neither of those approaches is very successful, and neither has the slightest thing to do with justice.
Justice is
securing to each person what he is due. What a person is due is what he has earned, or otherwise merits because of some action on his part. E.g., a laborer is
due the wages promised once he has performed the work; a sprinter is
due the gold medal if he wins his race; a lender is
due a payment at the time the borrower agreed to pay; a person injured in a car crash is
due damages from the drunk driver who hit him. Whenever someone denies another person something he is due, an injustice is committed.
Real crimes have victims --- persons who suffer injuries or losses because of deliberate acts by other persons. So one might suppose that the central purpose of a criminal
justice system would be forcing the criminal to make good those losses. Neither the punishment nor the rehabilitation approaches pay any more than lip service to that objective.
A real criminal justice system --- one that takes justice seriously --- would work like this: Once a guilty verdict is reached the trial moves into a second phase, a
restitution hearing. The extent of the victim's losses would be computed, using the same methods and standards used in civil tort lawsuits. The State's costs to locate, apprehend, and try the criminal are added to that sum, as are the costs of his ongoing confinement, if he must be confined. If he can pay that bill from his pocket, he is set free, unless he is a "habitual criminal," i.e., he has multiple prior convictions. If he can't pay from his pocket he is confined to a work center and paid at the prevailing market rate for whatever work he is qualified to perform, until his
restitution obligation is paid in full.
What if he refuses to work? Then he doesn't eat.
Citizens have no duty to "rehabilitate" criminals, or to feed them or house them. And merely locking them up for some arbitrary (and usually nominal) period of time does nothing to make their victims whole.
