Frankly I see a lot of people hating on her already but for me it depends on her backstory. It is already established that she is actually related to Keira, unless this is another Jeanette scenario form who mad me a princess (Cosette really reminds me of Ana, from a character design point).
So if she had a really shitty life while her 'sister' lived in luxury albeit not loved, there would be no reason to hesitate in killing her to take that place. Not that it's right, but unlike the father it has no betrayal or unnecessary malice underlying it

That's not the real cossette,.a devil is possessing her body. The real cossette is already dead and it was all tha fault of the father. You can't stop them to hate her because I myself hate her because she's a devil. She doesn't have any backstory, the real cossette has a backstory but not that devil who is causing chaos right now.

Lol we don't need romance ruining this story rn whoever the ML is idgaf but they better stay away for now they story is so interesting with out them. I know it's a story w/ romance but I wanna see her carry on with her plans for now. For some stupid reason everytime love is involved the MC become stupid, or questions everythingggg let her stay this way for some time. Although rest in peace for her child even if she gets romance it'll probably be hard for her to have children with that trauma
One thing I hate is when ppl give up perfectly good opportunities for lovers. I don't see why she would have had to choose one, but prioritise your life first
