We know that the Black Moon clan attacked Crystal Tokyo immediately after Chibi Usa took her mother's crystal, resulting in massive lose of civilian, not to mention destruction of the city itself. But do you think she's culpable for what happened? Were the Black Moon clan waiting for an opportunity to strike Crystal Tokyo and when they realized it was gone they struck? Or were they going to attack anyway, and it just so happened that it coincided with Chibi Usa taking the crystal? And do you think Chibi Usa, as a child (granted, a 900 years old child) should be held accountable for what happened?
I think the fact that Neo Queen Serenity revived most of the people who presumably died during the attack sort of makes this a bit of a moot point. But if she hadn't revived everyone (IMO there's gotta be some people who were beyond help. The Black Crystal that landed in the city was massive, those unfortunate enough to have been in the immediate vicinity of ground zero would've been obliterated upon impact) should a child be held responsible for lowering the defense of the city, and be complicit in the death of those who died?
