I was referring to that as well. That's where I put the guilt thing. She didn't want to involve those that weren't part of the guild since the whole fiasco was because the founding members got involved with Zeref. You can understand her reasoning a bit better if you really think about it. We've always known that while she puts on a strong front, she still harbors many doubts and misgivings about things. In a certain manner, you might say she is indirectly responsible for Precht going astray since it was she that first brought him into Dark magic and then due to her involvement with Zeref, Precht spent the remainder of his life devoted to research on forbidden magic.
