Even though she was evil, I kinda felt sorry for her. She desperately wanted to live, and I felt that. She was at her wits end making sure how to survive. How Disappointing would it have been for her to know that she was just getting played. And it's not that she resigned to her fate, even she fought against her fate, she even went with that ordeal to to change her fate. She deserved happiness. :(
I was upset that the red head had to die... She was such a pitiful character. She was basically the Villainess character that most isekai end up taking over. I do think you got the messaged mixed up though. See the roles are the bodies so the fate is only attached to the bodies and not the souls, the message was that despite changing roles to live, her evil actions still got her killed and Raelina survived despite being in a body destined for death because she struggled to survive while remaining a good person and not resorting to evil deeds. In other words actions have consequences
I don't agree with the ending/the messaging of this story. So no matter what happened, the soul that was Raeliana was going to end up dead? In the end, despite what new Raeliana said, the Goddess had the final say in all their fates.
