Most violent recidivists will need to be separated from society, often permanently. We do not yet have within our means the psychospiritual tools to substantively rehabilitate this small population, who commit a disproportionate amount of violent crime, including paedophilia, torture, and other forms of sexual assault and rape.
Within that contained environment, ideally all meaningful and possible means of non-violent growth and self-actualization should be allowed.
Even if they must remain contained and segregated from the rest of society for the remainder of their lifetime.
If they are let loose in the general population (in society at large or in prison), then many will feel compelled to act in either self-defense or in defense of others who cannot defend themselves, and to take a life. The responsible and compassionate thing all round IMO is to segregate, permanently, for the duration of this lifetime -- allowing supervised access to group work with other recidivists, and with therapists, teachers, faith advisors, and mentors -- in safe settings, etc.
Peace & blessings
