The Infant Spirit Reborn (Transmigration)

A pair of conjoined babies. One was saved and survived, while the other was separated from him and died a tragic death. In the form of a spirit, the dead child kept consuming the resentment that gathered in the human world, growing stronger and stronger. He could not live a healthy, complete life, nor receive the same treatment as his twin brother. From the moment he was born, he suffered the agony of being torn apart and left incomplete. He grew up, and became a demon... Then, when he was finally powerful enough, he killed his parents, his brother, and all the doctors who had performed the operation... And then? There was no then! Everyone was dead, yet he remained a spirit, wandering the world alone. He had seen through everything in the world and understood human nature, yet knew nothing at all about the living, breathing world! He was frightened and lost. Only after everyone had died did he finally learn what fear was. So... give him another life. What will become of him? P.S. This story is written in third person; only the prologue uses first person, so anyone who can't stand first-person narration can read on without worry. Reposters, please show some self-respect! Theme:
