Keep in mind she's given zero logical reason why she believes she's entitled to possess Shio.
I don't think most people think about "logical reasons" they're "entitled" to "possess" another person. And this is definitely not a story for logical reasoning. However, Satou has given two reasons:
1. Satou loves Shio, she was unhappy before, but she can be happy when Shio is with her.
2. Shio loves Satou, she was unhappy before, but she can be happy when Satou is with her.
Satou knows herself and her own feelings, so we can accept 1 as true. We have some idea of Shio's personal history and prior home life, and her awful flashbacks are instructive as well, so 2 looks to be true as well. Judging by the fact that Asahi lives on the street, it seems that Shio's options in life are to live with Satou or live in an orphanage. In the long run, I'm sure it'd be better to grow up under state care than to grow up trapped in the apartment of a murderer, however much you love her, but Shio's current environment is at least better than her previous one.
None of this is to say that Satou is "good". She is a murderer, a liar, a thief, and a manipulator. But she does have justifications for her behavior. In a sense though, none of that is important, since she is convinced that anything she does is justified, if it is for Shio's sake (or what she deems to be for Shio's benefit). The only real point Satou has in her favor is the sheer corruption of the world she inhabits, and the utter depravity of most of the other characters. Satou argues that Shio is too pure to be allowed out into such a horrible world. Within her possibly deranged worldview, her actions make perfect sense.
