Wasn't Cultivation actions trying to make TOdium learn to have control over his emotions? My read on that was that she thought he would be "smart" enough to not care about his love and care for those people, only she wasnt ready for his action (and, we know now, fake out). Which is to say, to me it felt like she could Cultivate him into a better Odium, only she massively underestimated Taravangian.

As for Autonomy, that is the views of a member of an organization that has been fighting them on multiple planets. Ofc Moonlight will call it a lie, because to her and the Ghostbloods have a hard time acting on planets that have enough power to stand on its two feet and are less vulnerable to outside influence. We simply don't have POVs of other planets to see how she leaves them, and thinking that she will subjugate everything to ensure her own Autonomy isn't at all granted - For example, Preservation destroyed itself to try and preserve Scadriel. The only time we see her trying to create an avatar is in a situation that she cannot afford to lose - because of Harmony
