You can set up a justice system that is designed to reduce harm and to make the victims whole.
But doing so seems to be pretty incompatible with seeing up a penal system designed to harshly punish offenders. Because harsh punishments do not seem to be effective at preventing bad actions that create victims.
Especially in the US, we've made the choice to have a penal system instead of a justice system. And so our system does not exact justice, it just passes down punishments.
I'm for drug decriminalization and all the various kinds of harm mitigation strategies to make drugs safer to use. But I also will admit without hesitation that modern synthetic opioids and amphetamines are black holes that consume a person's entire being. If we want widespread drug decriminalization we need to do a lot of other side work to stop people from being spaghettified. We need housing and healthcare and an expectation of a baseline dignified life for everyone because if your life is going to be without dignity either way you may as well be injecting heroin while doing it.
