"Judicial and penal institutions play a fundamental role in protecting citizens and safeguarding the common good (cf. Catechism of the Catholic Church, 2266). At the same time, they are to aid in rebuilding “social relationships disrupted by the criminal act committed” (cf. "Compendium of the Social Doctrine of the Church," 403). By their very nature, therefore, these institutions must contribute to the rehabilitation of offenders, facilitating their transition from despair to hope and from unreliability to dependability. When conditions within jails and prisons are not conducive to the process of regaining a sense of a worth and accepting its related duties, these institutions fail to achieve one of their essential ends. Public authorities must be ever vigilant in this task, eschewing any means of punishment or correction that either undermine or debase the human dignity of prisoners. In this regard, I reiterate that the prohibition against torture “cannot be contravened under any circumstances” (Ibid., 404)." - Pope Benedict XVI, yesterday.
