Contrary to what you have been told, not all residential school students were tortured.  Many were well-treated.  There are quite a few articles that support this, but they were drowned out in the pursuit of a political agenda.  The real torture was the attempt to abolish a culture within the parameters of a well-meaning institution.  We now know it doesn't work, but at the time, those involved really thought they were doing the students a service.  Stop comparing rez schools to the inquisition or crusades. Hardly the same thing.
