Everything went to shit, until now Sato was a sadist but hadnt diertied her hands (except the previos owners of their 'castle')
Not sure if Satou is a sadist. She doesn't go out of her way to be cruel, and she doesn't torment people for pleasure. Usually she seems very upset after interacting with the people she hurts (though admittedly, not out of any concern for their well-being, or regret for hurting them). She just does what she thinks necessary to preserve her love, regardless of any negative consequences for anyone else. I agree that with this she's definitely crossed a major boundary.
Without knowing how she acquired Shio, it's hard to judge her for kidnapping her—at this point, for all we know Shio was abandoned by her mother, or had run away, or she was abused, and Satou saved her. Likewise, her murder of the artist is maybe justifiable. After all, he was in the process of strangling Shio to death when she killed him. Every other case where she's manipulated or injured someone (like cutting those thugs' eyes out in chapter 7) is similar, where one could argue that maybe they deserved it, or she was acting in self-defense.
But her killing Shouko is absolutely immoral.
