'This throws one back upon a preliminary question as to the general principles upon which punishment should be meted out to offenders. In the nature of things there is no precise measure, except in the few cases in which the law prescribes one penalty and one penalty only. In all others, the judge must, of necessity, be guided by the facts proved in evidence in the particular case. The maximum penalty may, in some cases, afford some slight assistance, as providing some guide to the relative seriousness with which the offence is regarded in the community; but in many cases, and the present is one of them, it affords none. The function of the criminal law being the protection of the community from crime, the judge should impose such punishment as, having regard to all the proved circumstances of the particular case, seems, at the same time, to accord with the general moral sense of the community in relation to such a crime committed in such circumstances, and to be likely to be a sufficient deterrent both to the prisoner and to others. When the facts are such as to incline the judge to leniency, the prisoner's record may be a strong factor in inducing him to act, or not to act, upon this inclination. Considerations as broad as these are, however, of little or no value in any given case. It is obviously a class of problem in solving which it is easier to see when a wrong principle has been applied than to lay down rules for solving particular cases, and in which the only golden rule is that there is no golden rule.
