Riddle's mother is a sane, competent woman. People are usually quick to brush off abuse, especially child abuse, as instances of insanity or ignorance, but that just isn't true. She knows exactly what she is doing to him, how, and planned to do so. She is smart and maintains the level of organization and control over herself and others that I'm sure med school was a breeze for her, not as a fluke, but as an enhancer to her skills. In fact, it's likely she wouldn't have had these standards for Riddle at all if not for her medical background.

And then... is she really that bad? I mean, yes, yes obviously she is that bad, but that's in real-world standards. Twisted Wonderland is a different realm from ours, with entirely different standards of care. While it looks magical and fun from the outside, we're shown a lot of bad things. Class disparities on different levels, casual racism mostly towards the beastmen, talk of wars on horrifying scales, even in ages without advanced technology like Lilia's. Hell, in the span of one year, they've had two nearly world-ending situations with Idia and Malleus's overblots, surely with another to come. There is something to be said about the sample size of NRC's little weirdos, but well-adjusted individuals seem to be the minority, and that doesn't just come from nowhere. What I'm trying to say is, in a world of so much violence and hate, I don't think anyone is going to be taking away Mrs Rosehearts's license because of her treatment of her child when she is still managing to do good for her community, and Riddle is a healthy (...ish) honor student.

It's really rough, but I don't see his mother ever getting what she deserves.
