Harsher conditions are a deterrent  Worse prison conditions for particular offences would act as a deterrent. If people, in prisons generally and in society as a whole, see that those who are convicted of particularly bad crimes will be deterred from committing those worse crimes.  If prison is simply a holding place that prevents people inside from committing crime then it is failing in creating deterrence; criminals sometimes feel it is better to commit a crime when released in order to get back into prison. [1] Katz, Levitt, and Shustorovich using death rates show how harsh prison conditions are likely to mean lower crime rates overall – though a doubling of the death rate only reduces the crime rate by a few percentage points.
