is founded on the "eye for an eye, tooth for a tooth" incarceration philosophy, which essentially states that if one person harms another, then 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 imprisoning humans for life without a chance of release—that even death is morally and ethically a higher road than no-parole prison sentences. Deterrence The criminal is used as a "threat to themselves and others". By subjecting prisoners to harsh conditions, authorities hope to convince them to avoid future criminal behavior and to exemplify for others the rewards for avoiding such behavior; that is, the fear of punishment will win over whatever benefit or pleasure the illegal activity might bring. The deterrence model frequently goes far beyond "an eye for an eye", exacting a more severe punishment than would seem to be indicated by the crime. Torture has been used in the past as a deterrent, as has the public embarrassment and discomfort of stocks, and, in religious communities, ex-communication. Executions, particularly gruesome ones (such as hanging or beheading), often for petty offenses, are further examples of attempts at deterrence. One criticism of the deterrence model is that criminals typically have a rather short-term orientation, and the possibility of long-term consequences is of little importance to them. Also, their quality of life may be so horrific that any treatment within the criminal justice system (which is compatible with human rights law) will only be seen as an improvement over their previous situation.
