In regards to being heirs, her sister, A'una, is much more likely to take over than A'oma if anything happens. A'una though is a pacifist of sorts (I'll explain more on her page. ^^)

To go back to the point. Like a lot of cases of murders on Earth, nobody noticed anything wrong with A'oma's phycological state for the longest time. Her father is an incredibly busy man, and the only times he got to spend with A'oma and A'una, he spent teaching them his beliefs and about the empire, more than treating them like children. There's no point having heirs that don't realise what's going on.

During these brief times after the incident, the Emperor just believd A'oma was accepting his teachings well, and it wasn't until another incident when he had to intervene, and knock some sense into her. Since this second incident, he keeps close tabs on what A'oma is up to. The reason the emperor doesn't more actively confront A'oma about her issues is that A'una is doing it instead, and A'una is much better at it than him, so he leaves her to it.

The results of A'una's talks with A'oma are obvious to see in A'oma's more "controlled" eliminations. A'oma acts within the guidelines of the Ae'ani's teachings now, although  she still makes questionable choices at times. A'oma's difficult standards with her own race are also another issue, but this is simply a case of being a really tough teacher than anything deeper.
