It makes me wonder. She tried to kill Minako's good friend only because of Katrina going after the man Minako loved and not becuase Katrina was evil. I'm surprised Minako didn't perhaps tell Luna and Artemis of what Usagi did. It makes me think that in the S season when Kaolinite tried to steal Usagi's heart and it shows its very pure. I don't think Usagi is completely good, and perhaps because she abused her powers that way (I mean when she used her tiara in a bad way) maybe she's not worthy of being Sailor Moon or Neo Queen Serenity. I could be wrong. Just a thought.
