The opposition argument assumes that punishment must be proportional only to the suffering caused to the victim of a particular crime. Opposition state that for a sentence to be truly proportionate, it must reflect the subjective responses of the victim. This analysis fails to acknowledge that the definition of proportionality extends beyond the victim.  The four objectives of criminal sentencing are complimentary, not mutually exclusive. The aspect of a sentence that seeks to punish should be proportionate to offender’s crime, but in addition, it must not obstruct the functioning of the other objectives of sentencing.  A burglary may be upsetting for the victim, and incarceration of the burglar may seem a proportionate response. However, when that sentence is weighed against the imperative to rehabilitate the burglar, we discover that rehabilitation in prison would be less effective than rehab in a community setting. When custodial punishment is weighed against the imperative to protect the public, we discover that non-violent criminals who have been incarcerated are more likely to engage in violent crime following their release. The greater cost of incarceration- to the criminal and to the efficacy of the rehabilitative process- renders the sentence disproportionate.  The comparative popularity of imprisonment has distorted our understanding of which criminals it is most suited to.
