He's in the process of reviving. He was corrupted by Mother Goddess of Depravity, and sometimes there's a corrupted side of him that took control of everything for him. He stops his reviving process because he didn't want MGOD to destroy everything as he's still corrupted even after he died once. Anyway, he was corrupted once he went into Moon/Outer Space. There's a second book promised, the third is not really promised.
