Everything done to her ended in madness.
If she had gone tot he cops after the rape, instead of going along with the small hope she could still"debut", she might have saved herself. But like Yuzuki, she fell into the hole of justification.
Then she chose the fat guy who had only "stalked" her instead of the rapists or the betraying fellow idol. If she had let him go, intervened for him, she might have had a way to a more normal life.
In the end, her own actions made her crazy--her broken heart and broken mind were almost inevitable given her suffering and choices.
I don't think the girl deserved this kind of end.
