There is so much discussion of this packed into VC that there is no simple answer, this is up to every reader to decide for every character. It fluctuates over time, too.

I headcanon that currently none of the VC vampires we’re familiar with (not including PL) believe in a God/Gods, but I would say that they’re all open to proof, should there be a higher power(s). Most, if not all of them, have a healthy respect for voo doo, witchcraft, and other supernatural practices/beliefs.

Louis was Catholic as a mortal and he did struggle w/ whether, by nature of being a creature that exists by killing ppl (in direct violation of the commandment specifically about not killing ppl) he was therefore from Satan, and Lestat didn’t give him any answers on that:

“Because, you see, though Lestat had never said anything about devils or hell to me, I believed I was damned when I went over to him, just as Judas must have believed it when he put the noose around his neck.”

Hit the jump for more, cut for length.

Armand doesn’t have answers for Louis either, except to say that if Louis is from Satan, then he’s from God by default, too. Armand says: “all Satan’s power comes from God and that Satan is simply God’s child, and that we are God’s children also.”). Armand goes on to give what became the monologue in movie!IWTV about God not existing:

” `Then God does not exist … you have no knowledge of His existence?’
“‘None,’ [Armand] said.
” `No knowledge!’ I said it again, unafraid of my simplicity, my miserable human pain.
“ `None.’
” `And no vampire here has discourse with God or with the devil!’
“ `No vampire that I’ve ever known,’ he said, musing, the fire dancing in his eyes.
`And as far as I know today, after four hundred years, I am the oldest living vampire in the world.’

IIRC, Louis doesn’t talk about religion after that exchange, and AR doesn’t have him talk about it in later books, so we really don’t know what he thinks except that he goes on killing ppl so he must have reconciled it within himself. He and Lestat both like to hang out in churches, tho, so there’s that!

Armand and Lestat go through different phases of believing in God, and neither Lestat nor the others are really 100% sure about what he experienced in MtD (aka “Lestat Goes to Heaven and Hell for an Intense Job Interview, All He Gets Is This Crappy T-Shirt Veronica’s Veil”). But he does try to follow Marius’ example in slaying the evildoer, since they need to kill anyway.

Louis is indiscriminate, it’s whoever crosses his path, he doesn’t want the responsibility of judging someone’s goodness/badness, it’s more of a Savage Garden approach.

Claudia went to Europe looking for other vampires, but she was probably also hoping they had some magic/treatment that could make her body into an adult’s, Lestat dreams about it in TVL:

I dreamed of Louis and Claudia and that we were together. Claudia had grown miraculously into a beautiful woman, and she said, laughing, “You see this is what I came to Europe to discover, how to do this!”
