Separating the church (religion) and justice in medieval europe doesn't make much sense, as the church was the highest political power in europe back then.

I'm curious about how much do we actually know about was picked for sacrifice under the aztec rule. It seems like there is a consensus on this thread that all were innocent common citizens, but a lot of documentation shows that at least a sizeable portion of sacrifices were prisoners of war.

This doesnt make it morally more excusable, but it tempers your point as not everyone was a potential target of sacrifice.

A lot of "witches" and heretics tortured and executed in medieval times probably didnt do much wrong
