Meteion was an extreme empath. Every bit of emotion, from anyone, was felt by her. She loved Etherius, and it's people, enough that after witnessing, and feeling, the despair and grief of hundreds of dying worlds, she resolved that the end of existence was for the betterment of mankind. The fact that there were dozens(hundreds/thousands?) of them, meant that every single one, when they linked their consciousness, felt it and came to the same conclusion.
This one is more speculation, but it's due to the fact that if she did do anything other than what she did do, we wouldn't have had anything to go back to. It would potentially not have existed as per any time paradox that would happen from changing any major point in history. It at least allowed her to be able to prepare her champions in a way she saw fit to be able to at least attempt to stop Meteion.
