Seeing everyone almost perfectly fine after the last attack, the will of All Chaos almost lost its mind. In the last attack, she had used one of the world eggs and had sacrificed it. The world's eggs were something she had created after sucking the energy of the will of the world and giving it a different solid form.
She had only been able to create five such eggs even though she had been sucking the energy for thousands of years. So just to create even one of the eggs, she needed to work hard for many thousands of years. And now one such valuable egg has become worthless.
Will of All Chaos was unable to accept that fact. Even if egg was successful in killing all the attackers, she would still be sad about the loss. So the egg failing to kill even a single person was maddening for her.
