You know what, I think I know why I like The Torn Knight/Torn Basilisk.
They remind me of the concept of Lords of Shadow.
Hear me out, the Knight was supposed to help the suffering people, but gave into bloodlust, until they no longer had anyone to kill, before cutting themselves in half.
One half creates a new world, bringing forth healing water and life. The people it creates worship it, and praise it for their life, and the life of the world around them. It is everything Holy from the knight, in one being.
The other half, creates a plague. A plague with the only cure being the Healing Water. It's a monster. A shell of its former self. It is everything evil within the knight, in one being.
With the main character from 2000, destroying the Torn Basilisk, and bringing forth their own recreation of life... And their own Basilisk, as stated in the ending cutscene, "The world trembled and shook, shedding its dead skin and embracing the light"
What happened with the shed skin? The husk of what once was? I personally theorize that the land is in a never ending cycle of Self-destruction and Rebirth, thus the character bringing forth rebirth of the land, healing its woes and sorrows, but a basilisk of their own making is just below their skin, waiting for its own birth.
Now, in LoS, the Lords of Shadow are husks, filled with every unholy aspect of the knights they were separated from. These parts could not go into Heaven, so they stayed on Earth, creating their own centuries of destruction and chaos. Until a knight, most holy, was sent to destroy them. However, as his journey continued, he became corrupted by their darkness, since it had nowhere else to go, but him. When he destroys the final demon plaguing the land, known only as The Forgotten One, he recreates the world in a way.
The world is technically more peaceful, given there is only one source of Darkness on its planes, but that source of Darkness far exceeded any other that had walked before it.
