Sooo, yeah, she did horrible things to the MC, so I completely get the rage, and she probably deserves death, still, now that she has been bullied she has tasted firsthand the pain she had inflicted herself, she now understands a little bit more how MC must have felt, and that is compelling her to seek for redemption, to change for better. I at least recognize that's a good thing than not doing anything and let MC have his way and just kill himself, the guilt of having failed to protect him would eventually lead her to the same ending, and maybe that's how this story will most likely conclude at some point, but for now let's hope that there's a better outcome than that.
