Deterrence encourages the individual to calculate the costs of committing the crime. Punishment on the merits of the convicted offender is proportionate to the severity of the harm caused. This punishment applies to the specific crime committed and for no other reason. If the punishment is too harsh it is counterproductive and results in a lack of respect for the law. If the punishment is too lenient, it will not serve as a deterrent (Henry, S & Lanier, M, 2010). The concepts of classicism were not without contradictions and limitations. The first limitation of classicism was the assumption that people were equal. Pure classicism did not take into account individual differences. Even when the differences were clear, such as between adults and children (Henry, S & Lanier, M, 2010). Determinate sentences are intended to deliver fair justice and to make potential offenders aware of what sentences they might receive. This does not explain whether a given sentence reduces sentencing inequality among people convicted of similar crimes. Unless criminals think rationally before committing crimes, the deterrent argument makes little sense. Another related problem is that unless what the gain means to the criminal is known, there is no way to create punishments that counteract the gain (Henry, S & Lanier, M,
