I feel bad for the mom. Like, despite magitech being a thing here, I feel that they didn't invent things like therapy yet or such. They likely don't have ways of helping a mother deal with these types of anxiety-inducing problems.
The mother tried. Damn, she really DID try. She wanted her daughter to smile, laugh, and love her. Hell, she even brought back the maid that she had been jealous of for her daughter being more attached to.
It's just... she lacked the skills to be a good mother.
Does she deserve forgiveness? Not quite. She should, at the very least, try to do better to make amends and maybe then they can start to rekindle their bond.
