If, as BlueNight suggests, Jadis was the Antichrist of Charn, then the fact that she won the battle there and destroyed that world seems... un-Christian. Shouldn't the Jesaslan of Charn have defeated her?
Short answer: no. She was destined to use the Deplorable Word and end her world, then travel to Narnia to be defeated and judged there, at the claws of Aslan.
Christian doctrine is the canonical history of the Earth in the Narnia multiverse. That Earth has an Israel descended from the nation rescued from Egypt by "I Am". The story of that Earth is the story of God's covenant with that Israel and Christ's covenant with that Earth's Church. We can presume the final end of that Earth matches Anglican eschatology of Lewis' time.
Narnia's apocalypse was different. Aslan brought an end to that world shortly after the deception of the crafty ape and the unwitting donkey.
Each world (universe?) in the Narnia multiverse is portrayed as a pool in the Wood Between The Worlds. Our trope-savvy storytelling minds might reasonably assume that each is a universe with its own cosmology, but possibly with more planets inhabited than just the main one. (Is the Earth of the Narnia books the Earth of the Perelandra Trilogy? The latter is also supposed to be Tolkien's Middle Earth, which makes it quite a crossover mashup! Also, Digory's uncle forged magic rings...)
Upon the unique end of each world, every unjudged sapient gets sorted into Heaven or Hell (and the Heavens all meet in the middle).
So in the universe of Charn, Jadis caused the immediate judgement of all souls except her own, due to their sudden death from the Deplorable Word. In all worlds of the Narnian multiverse, the Incarnation of the Logos is God Himself, omniscient and omnipotent. He would not have allowed Jadis to use the Deplorable Word if her doing so wasn't His plan to end the world of Charn. (Then we get into theodicy and the problem of pain on a multiversal level, but not here, please.)
