Okay, I just reread the story and then read the backstory for Anna. Idk if I forgot the specifics of her backstory or just never read it, but it solidly changes how one sees Anna.
She just killed all the remaining survivors? Wow. No wonder she doesn't want to hurt anyone else again. I kinda just thought she was a bit of a pushover as a result of trauma and failing to protect people, but nope. Anna is not an innocent pushover. She is someone who thinks she went overboard and now never wants to give herself a chance to hurt others again.
To be clear Anna didn't kill
all the survivors. What happened is she returned one day to find the people who believed
Anna was the cause of the Antagonist attacks trying to murder those who disagreed with them. They refused to back down so she did the only thing she could to stop them; kill them. The survivors of those who still believed in Anna were left behind while Anna went off to destroy Saskatoon Breach only to be killed by Antagonists* while she was gone.
*This bit is a little theory of mine but I think this was Sekhmet's last laugh. It had
escort Antagonists who were sent away because Anna was using them to resupply. Where did those Antagonists go? My theory is Anna's hometown; all the local Antagonists were culled for quite a distance so some stragglers stumbling across Anna's hometown, when it was a known danger zone, seems unlikely. Not when Sekhmet's escorts were
right there. It would also fit nicely with Anna's trauma onion; she
didn't stop them, albeit because Sekhmet was nearly killing her but I doubt that matters to Anna, and they murdered her hometown.
Also I don't thin Anna thinks she went too far. She hates unnecessary human on human combat because it reminds her of that incident but she is perfectly willing to kill again if necessary:
So she didn't even notice.
You response tersely.
>Sweeper 1: You would have hit humans.<
>Sweeper 4: What…? So?<
…
Your heavy particle projectors swing around and lock onto the threat-
and while that was the clearest indication of Anna planning to frag a threat there are hints she has come close to that point before for example:
Disciplinary action appeared ineffective so far; just this year alone, she had already accumulated four warnings and a week long suspension of Valkyrie frame privileges due to incidents with–
You shift your stance, Impeller thickening, Durga's components just barely held back from extending out into existence.
–your Flight, Shuri and Yukari in particular. Shuri had been unresponsive to Javeria's provocations, simply documenting them and filing complaints with the Instructors, so Javeria had instead turned her attentions to the other members of your Flight-
"What do you want?" You demand before Javeria can answer your previous question.
-If the adults can't do anything, you will-
There are hints throughout this scene that if she didn't get good enough answers Anna was preparing to
remove the problem.
If anything I think Anna has learned the
opposite lesson for what happened in her hometown. There she left things alone and let the conflict bubble away until it exploded. Now she is hyper-aware of conflict and prepared to jump to extreme violence to end it. While she is absolutely heavily traumatized over killing those people she is
even more traumatized by her
failure to defend those she promised to from them and now will
never allow another situation in which she fails to defend people from Antagonists
or other humans.
