Okay, so I just compiled a list of roles related to death:
Resurrectionist: town, can resurrect a dead player once.
Mortician: town, learns the role of a dead player.
Pathologist: town, gets the system messages of their dead target.
Exorcist: town, chooses a dead player so they cannot be revived.
Ghost: town, once dead, can roleblock an alive player per night.
Ghoul: town, chooses a player, if the Ghoul is targeted for a kill, their target dies instead.
Medium: town, can summon a dead player.
Mourner: town, can ask the dead a question.
Zombie: 3rd party, infects people.
Vengeful Spirit: 3rd party, I'm not sure I understand epicmafia's description... I think it works like the Ghost.
Phantom: 3rd party, wins if dead by the end of the game.
Poltergeist: mafia, once dead, can roleblock a person per night.
Necromancer: mafia, can resurrect a dead player once.
Ghosthunter: mafia, chooses a dead player so they cannot be revived.
Graverobber: mafia, steals all the items and reports a dead person has. Not in the maf chat.
Mummy: mafia, once dead, if a player visits them they'll die.
Hypothesis 1:
- Castiel just put his foot in his mouth and claimed.
- He is the actual Graverobber.
Hypothesis 2:
- Castiel is the Ghost or the Poltergeist and claimed a maf role so he can be killed and use his NA.
- In my opinion, either the Ghost or -especially- the Poltergeist are bad news for the town rn. I'd recommend the exorcist to banish them forever.
Hypothesis 3:
- Castiel is the Mummy and wants to be killed to activate his ability.
- In such case, he should not be visited.

I'm inclined to believe in hypotheses 2 and 3. In order to avoid losing the exorcist next night, I'd wait till next day. If somebody has been roleblocked, please say it and we'll know that Castiel was the Ghost/Poltergeist. If nobody has been roleblocked, then he might be the mummy and therefore nobody should visit him.
Another option is that we just leave Castiel alive, nullifying his possible ability. And I think it's the best option. So:
[Unvote] Castiel
