" She tells Minerva that she's there because she's gathering soldiers, but she didn't have use for weak soldiers so she killed everyone in the guild"

Wrong. She's using her Magic on them to boost their power... almost like Ultear boosting people's Magic I think. If they can't handle the surge in power they shrivel into the paper people. She's not technically killing them because she thinks they're weak... She's just using her Magic and hoping they're strong...
