The theory is basically she did what she needed to to stop the Grimm targeting her. Her brainwave was that, as Grimm seemed to appear as fast as you kill them (maybe even faster) maybe the solution was to stop them seeing humans as an enemy to destroy. The threat would thus be no more without any more fighting. The problem is that the modifications she made to her body to that end warped her mind to the point where she actually started thinking of millions of dead as eggs broken to make an omelette.

As I said, in this theory, the woman that she once was would have been repulsed by the thing she became. However, there isn't enough of that person left anymore.
