Thanks for the thoughtful and detailed response. I see your points and I think you've brought a valid interpretation of the facts in the game. The part I disagree with you is that you are assuming Garnet's action are rational, while I believe that her actions are not rational but rather a consequence of her traumas and fragile psychological state.

In fact, it would make sense that she is confronted with consequences for her actions, regardless of them being rational or caused by trauma. That's a good point. I think, from the writers' perspective, it might be that that they had put her through so much hardship that doing that would be too harsh.

You could rightfully point out that the same mercy is not given to Zidane and Vivi, for example, which I agree. I think both of them as still the sort of masculine-hero persona that are written to be strong and simply power through hardship, while they also deserve their fair share of grief and empathy.

In any case, I still think Garnet's arc is well structured, developed, and written, even with its flaws and shortcomings. I cannot say the same for most of the other characters, even if they are more symphatetic or are mainly "good doers". You might be confusing the writing quality with how symphatetic or likeable a character is, which were not my points. Freya is likeable and symphatetic in FFIX, but she is sadly badly written and underdeveloped (her arc does not even finish and she is mostly forgotten by the plot after a while).

Again, thanks for taking the time to read and reply to my text.
