Prison reform is the attempt to improve conditions inside prisons, aiming at a more effective penal system.

Theory

Retribution/Vengeance/Retaliation

This is founded on the "nail for an nail, nose for a nose," incarceration" philosophy, which essentially states that if one person harms another, then an equivalent harm should be done to them. One goal here is to prevent vigilantism, gang or clan warfare, and other actions by those who have an unsatisfied need to "get even" for a crime against them, their family, or their group. It is, however, difficult to determine how to equate different types of "harm". A literal case is where a murderer is punished with the death penalty, the argument being "justice demands a life for a life". One criticism of long term prison sentences and other methods for achieving justice is that such "warehousing" of criminals is rather expensive, this argument notwithstanding the fact that the multiple incarceration appeals of a death penalty case often exceed the price of the "warehousing" of the criminal in question. Yet another facet of this debate disregards the financial cost for the most part. The argument regarding warehousing rests, in this case, upon the theory that any punishment considered respectful of human rights should not include caging humans for life without chance of release—that even death is morally and ethically a higher road than no-parole prison sentences.
