Michel Foucault Plays D&D. Thoughts While Reading Disciple & Punish:
In discussing premodern (before the last couple centuries) punishment in European legal codes, Foucault discusses various ways the body of the condemned is made to testify to the finding and sentence, a second testament for those who can’t read or hear the official verdict. Among things this leads to making it a repetition or extension of the original crime to conceal it.
So in Fantasyland, where there’s presumed a certain level of healing magic around, the law includes a time span in a judicially imposed wound cannot be cured. It’s like a parole period. Anyone who modified the wound, either cure or to worsen it, before the period is up can be found due the same punishment and also guilty of a separate crime against the sovereignty and righteousness of the magistrate.
Naturally, in evil situations, secretly healing the innocent is a very moral but dangerous thing to do.
