Confused about something *spoilers*

Wasn't it told over and over again that the goddess dies once Caius is defeated since he was blessed with the heart of chaos or whatever.

Then why didn't Serah and Noel realize that everything was going to consumed in chaos once they DID kill him, and why did they make it their motivation to kill him, knowing that killing him was going to unleash Valhalla?

I never understood that.

i thought they wanted to stop him not kill him.

But even after they DID kill him, why did they assume everything was going to be okay, until the ending of course...
