Within the criminal justice system one of the most prominent justifications for legal punishment, both historically and currently, is retributivism. The retributive justification of legal punishment maintains that, absent any excusing conditions, wrongdoers are morally responsible for their actions and deserve to be punished in proportion to their wrongdoing. Unlike theories of punishment that aim at deterrence, rehabilitation, or incapacitation, retributivism grounds punishment in the blameworthiness and desert of offenders. It holds that punishing wrongdoers is intrinsically good. For the retributivist, wrongdoers deserve a punitive response proportional to their wrongdoing, even if their punishment serves no further purpose. This means that the retributivist position is not reducible to consequentialist considerations nor in justifying punishment does it appeal to wider goods such as the safety of society or the moral improvement of those being punished.In this chapter, I outline six distinct reasons for rejecting retributivism, not the least of which is that it's unclear that agents possess the kind of free will and moral responsibility needed to justify it. I then sketch my novel non-retributive alternative, which I call the public healthquarantine model. As we'll see, the model draws on the public health framework and prioritizes prevention and social justice. I contend that it not only offers a stark contrast to retributivism, it also provides a more humane, holistic, and effective approach to dealing with criminal behavior, one that is superior to both retributivism and other leading non-retributive alternatives. I begin by taking a closer look at the retributive justification of punishment.
