Johannes Cabal has never pretended to be a hero of any kind. There is, after all, little heroic about robbing graves, stealing occult volumes, and being on nodding terms with demons. His purpose, however is noble. His researches are all directed to raising the dead. Not as monstrosities but as people, just as they were when they lived: physically, mentally, and spiritually. For such a prize, some sacrifices are necessary. One such sacrifice was his own soul, but now he sees that was a mistake - it's not just that he needs it for his research to have validity, but now he realizes he needs it to be himself.
