Now this is interesting! Heresy not in defiance of their goddess, but as revenge for the evil underside of the Milisto Church. Alotte's apathy toward Emilia as a concept versus the very natural empathy toward the genuinely kind airhead that she is.
It's also interesting that Alotte's hometown is called "Hidden Church" - that means that for centuries, the Milisto Church has been doing this crap, but without even the foresight to try to manage the villages like a real eugenics program.
It's also sad that Alotte's parents tried so hard to make her a saint, not out of greed, but a misplaced sense of love. They genuinely thought making her a saint would make her happy, so they mindlessly followed that minister's orders. Even so, they still gave their lives so Alotte would live. They fucked up, but I can't say they didn't love her.
But who are the other candidates in that minister's plan? Yes, we know their names, some of them. I mean their jobs/roles.
