I mean, in a way I kind of feel bad for amarylis, since she was totally ignorant. But the ...

I don't know, personally (so this could just be me) Amarylis doesn't seem to be written as just evil. She's selfish and cruel but also foolish and naive, so she's not written as a sympathetic character by any means, but she definitely feels like a tragic character who you're meant to pity but not support. I think this way based on how she seems to be treated as no more than a means to an end by the priest who she sees as the only person she can fully trust or rely on, while he's shown he's will lie and cause her harm without hesitation with the recent poisoning incident and with how he's kept her in the dark about her identity all this time

So yeah, I don't think the author means to just write her off as evil, and I think that these feelings of pity you feel are definitely purposeful, but I also doubt the author intends to give her any redemption or happiness in this story
She's a tragedy we're just supposed to watch with hungry eyes as she inevitably inflicts more pain on not just others but herself as she's used by the true villain until her inevitable downfall

(This is all just speculation on my part ofc :>
You could honestly be totally right, these were just my thoughts)

Yeah I know what you mean, I pretty much agree with you.
I know its really stupid to say this but my main complaint is that it lacks realism? it didn’t take much for amarylis to go straight to murder when shes supposed to be this lovely princess, she just went crazy and did it. I think telling it this way is too farfetched and diluted the immersion, although its not the most immersive story and make lead 2 is pretty forced in my opinion, he is also another plot device

Yeahhh, I totally see where you're coming from
The only response I can think of is that Amarylis has always had the "lovely" facade but always had the superiority/inferiority complex when it came to Ashtarte. She was always cruel and whatever kindness she showed had a level of "I'm better than you" to it, and now when shes met with the truth, she's still in denial about how everything she's had has been stolen from Ashtarte. She now sees Ashtarte as a threat but views her as a thief who wants to steal everything from her (I think it's projection of what Amarylis would do if in Ashtarte's place and has done in the past)

Personally, I think it is pretty realistic because it reflects how an abuser/manipulator/oppressor reacts when their victim gains an inch, even if things aren't even close to equal, they see it is a reversal of the oppression and harm they've caused where they are now the victim

Maybe not the murder part, so I can see why that feels weird (to me it still doesn't seem too out there cuz Amarylis was never really shown being particularly against murder, so it doesn't seem like a huge change, just that she's now tipping over an edge she never resisted in the first place)

But a big part of it is just that this story speaks to me and connects to my real life experiences and world view in different ways, so to me it is an immersive story
And I can totally see that from another perspective that wouldn't be the case
(Sorry for the essay-long responses ....)
