In fact i love the morally debatable story like this, im totally bored of morally good, "villain" only in title or power of love and friendship story. This series kinda reminds me of Overlord... for what Ains doing. And most of all Aria is totally consistent of what she wants to do, personally i have no sympathy towards Mielle, the girl who dares to push her own father (the thing Aria can't even do to her mother) into disability. In the end she got what she deserved, Aria as well already got punished in the first timeline, both of them are kinda balancing each other...lol.
