I can understand it but that’s not the real question is it? The question posed was why one person was treated differently by the courts than the other.

The answer was because one person attacked their active abuser in self defense while the other escaped,then months later, in an act of revenge, planned and executed their murder and arson.

Of course, another key difference is that she took a plea deal. Which means she never actually went to trial. Her legal team knew self defense was never gonna fly either.
