If you asked me what was the most EVIL thing we've seen from a character so far, Pyeka's sacrifice scene is definitely up there. It's presented as being deranged and messed up from the music and dialogue, even if you consider her "I'm your afterlife" claims to be true. She's gobbling up dozens of people who are totally loyal and devoted to her instead of doing anything to actually help them out as outcasts and exiles of her former kingdom. Even Naya, another character who is notorious for eating people, doesn't go after her own kingdom's citizens. Don't mistake Pyeka being polite and nice for not being evil, imo.
