Like what the Supreme God of Life said, since most of the Gods that have died are those who actively pursued and fought against Kireina, or at least members of a Pantheon that did so, Kireina isn't percieved as a threat. Furthermore, she hasn't killed anyone under her protection, nor attacked anyone unprovoked, nor even destroyed any territory just for the sake of destruction. The World Will and the Supreme God of Fate have made her an enemy by their own accord, but that doesn't mean she will destroy the world.
