My comments will be in bold

Basics and grounding

Cool, we love an apocalyptic universe.

Character information

This works I suppose and all of the information is fine, but if you want her to be a character that the audience sympathises with then you're going to have to add a couple of positive traits to her personality because a tragic Backstory doesn't always cut it.
Even if you choose to not do this, develop on these traits more and potentially research manipulative personality disorders to really push forward this narrative.

Relationships

Okay you gotta be careful writing relationships like these. I'm not saying it can't be done but I think you need her to have a relationship with at least one living person so that the character feels somewhat realistic.

Backstory

Okay so this is obviously building her up to be a kinda antagonist but you need to describe her life before the murders, including positive moments that connect her to her mother and sister more. You also need to be able to show the trauma of these events so research real life events like this and how the people reacted to them.

Other

These are fine and the theme song fits so no issues here.

Stats

Stats are pretty well balanced so there's no issues here.

Final thoughts
I think that this character has the potential to be pretty good, but you've gotta work on her and shape her a bit more so that she feels more realistic and fitting.
