You can stop at “murdering insane”.
I don’t think Elsa should be considered a yandere. The point about them is the opposition between how they are initially perceived (are?) and how they shift and end (i.e. cute, kind girl turning murderous insane). None of the girls in GSG match this description: even if they turn against their handlers (the way Elsa did – better explored in the anime than the manga, BTW), it’s a logical and not really surprising consequence of their situation (if anyone cares to follow/understand them, of course – what Lauro didn’t) IMO.
People have to understand that “yandere” is a newly coined word in the otaku lingo. Of course, since it being made “popular”, everyone is looking back (and forth) and trying to apply the word to everyone they know (the way the words “tsundere” or “moe” are now overtly used and abusively used to describe everything and the rest), but it started with a pretty exact concept in mind.
…from what I heard at least, because I’m not a 2ch user, nor an otaku therefore not very knowledgeable in their mysterious ways.
