I'm ready this from the start again after a long time, and I've got little sympathy for the MC's ordeal from the setup explained in the 1st chapter. She wrote the novel, so she's responsible for the backstory of her villainess. She's the one who was perfectly fine with writing a character that has to live through abuse as a child only to be killed by her MCs and suffer for eternity in some version of hell. When she complains that "the scariest thing is a future without hope" and that even if she dies, it's better than suffering, all I can think is "boohoo, just drink your own medecine".
