Man, looking at 200, I feel like it would be such an easy fix to tweak it so that

1) Usagi’s compassion and hesitation comes from recognizing Galaxia as someone who started off wanting to do good and then went so, so wrong, and Usagi grappling with what the differences between them really are (with part of that being killing people vs. letting people die for you, maybe) (BUT HER THING ISN’T JUST I DON’T WANT TO FIGHT AND MASS MURDER IS OKAY. LET HER THING BE “IS THIS WHERE I’M HEADING TOO?”)

2) Having Usagi absolutely stab Galaxia, BUT WE CAN STILL LET USAGI BE USAGI AND SKIRT AROUND STRAIGHT UP KILLING (though like, Beryl called, she wants to know where her redemption option was) BY HAVING USAGI’S POWER BIRTH GALAXIA’S STAR SEED ANEW. (Usagi sending it off to be reborn with a “Do better this time. And I will too.” Yeah? YEAH??)
