What is the test for determining the appropriate sentence for a convicted rapist?

The determination of an appropriate sentence requires the exercise of discretion after due consideration given to, among other things, the crime charged, the particular circumstances of the individual before the court and the purpose of a penal sanction, i.e., societal protection, rehabilitation and deterrence.... Just as the court must be free to impose a more severe sentence when warranted, the plea and sentencing process must leave the court leeway to consider a lesser penalty when the facts and justice so require.
