There is no victimless crime, you can practically always find someone directly or indirectly harmed by it. The idea of rehabilitation is that victims may have the right to restitution or reparation (to be made whole, or at least approach that state) but not to retribution. The punishment of a criminal is supposed to provide the basis for his eventual rehabilitation, not be driven by the victim's or society's desire to make him suffer for his "evil" deeds. I think the historical evidence is that this is the preferable approach to building a society and that OPs idea that social peace requires punishment is wrong.
