What can you and can't you do? You seem to have a pretty solid transformation going. Since you are so far along. why do you think this happened?
Can angels die? I can see vampires in purgatory for the simple fact that they chose to stay instead of a vampire version of suicide. Vampires eventually kill, choose to live off of blood at the very least.
It's not your fault. As a non-believer, I didn't expect much more than a pine box and earthworms in my skull.
