Again, they built the schools to operate the same way as other Catholic Schools around the world, and then the Canadian government decided they were going to take on the entire native population, mandated by law, without offering the resources to even keep that many kids fed.
The Catholic church ran those schools (and likewise the other Churches with theirs). If they didn't have the resources to run them properly, and it was bringing harm to the pupils, then they should have shut them down.Indeed. Don't see how Catholicism or the Vatican is to blame for the shit the Canadian gouverment did to its native population.
You can talk about objectionable policies and under-resourcing from central government all you like, but the welfare of pupils in a school is the primary responsibility of those who own and run the school. If they could not accomplish a proper standard of care and continued to subject their wards to neglect and abuse, they are at fault. They had responsibility over vulnerable individuals from a societally vulnerable group, and failed them. They failed them as part of a general culture of contempt for their charges and were absolutely complicit in this tragedy.
No excuses.
