She took her from the street, which means she didn't actually kidnap her (kidnap, verb: abduct (someone) and hold them captive. Satou is doing no such thing).
The reason she doesn't tell the authorities are because they would take Shio back to her mother (who left her out there in the first place). Then she doesn't go further because she's scared of what might happen to Shio. These are minor reasons, mostly she's doing them for personal reasons, but they are still there.
I'm not saying she's a good person, but if you just write her off as crazy without considering any of the other details that the series presents, you're not going to get the entirety of the series.
Also, if Shio told her that she wanted to see her mum and/or brother again, Satou would let her do it (after Shio begs hard enough), because she wants Shio to be happy.
Most of that is irrelevant. You're not allowed to just take a kid, willing or not, into your house and house them there for an indeterminate amount of time. Especially someone under 5 years old, and this goes for a minor of any age in Japan. Young children are especially susceptible here. They do not have the mental capacity to decide what is right for them. You will get charged with kidnapping regardless of the opinions of the child. This is especially murky in Satou's case because of the nature of Shio's mental state. She's a child in a precarious situation and some "good Samaritan" takes her in and showers her with the "love" she desires. It's all kinds of messed up.
The reason she doesn't tell the authorities has nothing to do with her being reunited with the mother being a bad thing -- it's because she doesn't want to give her up. Shio is her "soul mate' and nothing is going to stand in the way of them being together. I mean she's pretty open about this fact numerous times. That's basically what this whole story is about. She murdered people to stay together.
You say she'd let her see her parents and brother again (whom I can only assume Shio has actually forgotten at this point due to the trauma of her past) but I have my doubts. Considering the lengths she's going to throw her brother and others off the scent, down to outright murder. I do not believe Satou would be able to cope with letting her go.
Honestly, my heart breaks for Satou. She finally finds something she can care about and has effectively fallen off the deep end in an attempt to keep it hers. It doesn't really detract from the seriously depraved path she is treading in this futile effort.
