Even if Hisui wasn't the one who originally came up with the Eclipse Gate (I mean the original idea of killing Zeref in the past), she certainly was the one to fall for F-Rogue's lies and changed it into the Eclipse II Plan.

To make matters worse, Lucy told her to close the Gate, but Hisui refused to listen until the first Dragon was already through.

And the final nail in the coffin was that Hisui was completely helpless to do anything and had to watch Lucy and Yukino close the Gate, probably shattering what little self-confidence she had left.
