I agree with you, man. No matter how we see that "that" woman isn't fit to be a mother, for an orphan, a mother is still a mother no matter how they ignored and left them. She's been longing to have one and so when she met her, she has this hope that she will somehow think of her like how a mother should, at least once (when testing her mana) and she realize she really no longer cares about her when the woman refused.
Yes. That's why i can't blame lilith because i was never been her so i never knew but if i were her, and i were in her position. I will also crave the same love especially whenshe found out that a father's love is nurturing and unconditional. She thought maybe her mother had her situation that's why she chose to do what she did. As we all know lilith is still have an adult mind that's why she understands all the possibilities yet still craves for something we all called "mother's love".

why does lilith want to get along with her mom???? she was literally told that her mom sold her off to keep her other kid safe?? and lilith is mentally an adult so she should understand that her mom's a total bitch?? I dont fucking understand and its pissing me off??? the fucking brother also literally lied and she's just??? passing it off??? hello? am I the weird one here?? even more lilith is an orphan? so she should understand what it means for someone to not want anything to do with their kid? why the fuck does she give a fuck about her? shouldn't there be resentment??? plus she has a great dad so the contrast with her pervious life and current one should give her some insight into who is not worth keeping around right????
