Aria's mind was a complete mess, she did not know what the right decision was in the current situation, the whole situation itself was messed up and even she with all her knowledge and abilities had no clue for what should be done or what actions should take from here.
Aria has three kids, and she has a family but she doesn't have the emotional bond pertaining to that family, only the soul and body like lay, and for even a moment the thought of killing her clone Grace and taking up and living the life of a mother to these three children passed through Aria's mind but those thoughts didn't last for long.
