Shitty parent - check
Shitty gods - check
FMC was chosen to be a Saint because she was selfless, dedicated to people other than herself, but can it still be called selfless when it was forced onto her as such a young age? She finally had her own life, and died because of gods mistake. And to rub salt into the wound, her second life was another tragedy, having both her supposed parent died and she barely survived if not for the bunny doctor. Worse, the gods probably "aid" her by tampering with fate to make her become a Saint as soon as possible.
I rambled so much, even though it's a fiction.
