Just think about the logistics of resurrection for a second, will ya?
When a person dies, their soul leaves their body. When a cadaver is resurrected, a new and different soul has to take its place to give life and character to the corpse.
Oh, also, this new soul will likely be evil.
If you were a soul in Heaven, trust me, you would not want to come back to Earth in some old, dead guy’s body.
New life with an evil soul. We monsters tend to think this is how it should be all the time.
