Recently went over the transcripts for Amane's interrogations, and it's very interesting stuff:
• Es physically reprimands Amane during the end of the T1 interrogation (and subsequent start of her song)
• Amane despite her age and maturity, believes herself to be as mature as an adult (Most likely due to her trauma, trauma tends to embolden someone in things they shouldn't be), going as far as to be aggrevated when people look down on her as if she were a child
• My longstanding beliefs of the effects of T1 on her seem to ring true, she goes from being an optimistic girl who talks of her teachings, she mentions her parents scolding her for at minimum an hour for her mistakes and she actually takes the role of the primary speaker in the interrogation. Whilst in her T2 interrogation she's broken, less talkative and more prone to outbursts (She attempts twice to attack Es with scissors, threatens Kazui, and despite using "We" for the beginning of it, she switches to "I" when angered). She also takes heavy note of the fact Es refers to himself as "We" near the end, now unsurprisingly I am not exactly going to read/listen to over an hours worth of transcripts, but if any of the other inmates figure out that Es isn't just Es, let me know. But as I believed and interpreted through the songs, by marking her innocent in the second song we emboldened her zealous nature.
The interrogations have told me that the first trial is something the inmate doesn't expect to happen, Amane is so determined to be innocent or her murder, yet her subconcsious begs for forgiveness of her sin. Deep down in Amane's heart is a little girl that was tortured into what we see in T1, and the guilty verdict not only destroys her outward persona (A Big Girl who just does what god wants) but her subconcsious (A little girl who just wanted to help people and animals in the name of her god).
T2 and what it does to her is a result or breaking that little girl in half, if T1 is her childish subconcsious, T2 is her religious subconcsious, she no longer wishes to be forgiven (neither by us or her cult), she doesn't believe in the systems she's apart or (again, MILGRAM and the cult) and because of that, Purge March is Amane's declaration that she is the only force who can provide the will of her god, neither MILGRAM nor her cult are correct, only her and her faith and because the verdict was innocent, we reinforce the idea in her head that she IS the hand of god and thus should be the one who decides who sins and who doesn't.
Amane is gone, what is left is the girl who survived the torture and cleansed the world of those who sinned.
