Normally I don't condone violence against children.
Fortunately, this is clearly some sort of ancient demon in a child's body that must be cleansed with fire.

Not a small child but adult/young-adult.
Already established relationship with room to grow, so unlikely to devolve into harem.
She's intelligent but a tad ditzy, so not perfect at everything.
Okay, this seems like...
It always feel like these big evil groups are run by morons which always begs the question: "If they're so stupid, how did they get in this position?"
In this case: It's nice sometimes seeing reasonably competent villains.
I really want to give them shit for the whole "He's handsome so he must be suspicious" thing, especially since it's obviously because Albert is supposed to be ugly.

Two things:
1) From what I understand, the artist's fanbox has onee-shota art of these characters. So the implication is definitely still there.
2) The reddit link to this chapter on r/manga got removed by reddit themselves, so at least someone disagrees with you.
Median income in Japan is ~472,000 per month. So it's pretty damn low. However, since she's living on a mountain in a fantasy world, she doesn't have to pay rent or utilities. So it's actually pretty good.
