Some criticize the Catholic church, Christianity, for what Cortez and others did...
Just as a point, Catholicism (which is Christian, note the founder), is never behind murder of any sort. By definition.
People in the Church, people who are baptised Catholic, even the hierarchy, can say they are Catholic, but that does not necessarily mean they are practicing Catholicism.
It does mean they will be judged as Catholic, whereby if they had been lying and murdering it doesn’t go well.
But Catholicism is never behind this kind of thing.
