You can’t redeem someone who is unwilling to acknowledge guilt, repent (turn away from the wrong behavior), and seek redemption. Until and unless the individual reaches that point, your idea is really unworkable. It would merely keep others in harm’s way. This is true of sinners and of those who suffer mental illness’ alike. Healing must first come from a heart and mind that are READY to BE healed. The adage “You can lead a horse to water, but not make him drink” applies here as well; and it’s just as wrong to place others’ lives in harm’s way, in an effort to reform the justice system as any of the other notions of such reform, that have come down the pike over the centuries. It looks nice on paper, but the reality would not be.
