Kelemvor, the God of the Dead (who hates undead more than any other).
It's likely to be a pretty widespread thing, that, no matter what your pantheon.
God of Battle: really prefers fallen warriors to stay dead.
Goddess of Beauty: not going to like Zombies or Nosferatu.
Goddess of Putity: ditto.
God of the Cycle of Birth and Death: infectious undead are an abomination to this guy too.
Goddess of Nature: they're as unnatural as they are undead. Hatred incoming!
God of Death: undeath is downright insulting to him, so, yes, he's going to hate them too.
God of Earthworms: earthworms can't digest corpses that are walking around. Even this guy's not going to like them.
God of Volcanoes: not really concerned one way or the other, but feels he ought to join in for the sake of family.
Goddess of the Oceans: zombies trying to walk across the ocean floor Do Not Belong. Divine Great Hammerhead Shark, it's time to clean up.
