Would it be best for Ashis sisters to return as well as herself

We may have seen that due to aku being killed in the past ashi faded away from existance due to being her daughter in the future but wouldnt her sisters as well, well that would apparently be the case as well. Whether they were dead or alive they would've never been born but if they were to come back they might actually end up being good or probably end up evil again that is therefore jack might have to kill them again i don't know what i think is that either they were the same as Ashi or she was the only that was good while her sisters were apparently were evil. It's just that she has seen the beautiful things in world more than her sisters. Tell me what you guys think would it be best for Ashi sisters to return as well ,leave your comments below
