When the last interned patients left the oldest criminal lunatic asylum in Italy, the author questioned the moral economy of the process of overrunning this type of institution, in particular as this process was allowed, supported, or in any case accompanied, by an upgrade, a reclassification, a moral restructuring of the collective image of the institution, which has led to a shift of status from a lesser evil to an extreme evil, from a necessary and tolerable evil to an excessive and unacceptable evil. A moral upgrade took place in a short time.
