My Dad's a Christian (I think) and so I asked him if God made it possible for angels to kill natural-born demons and he said yes. If this is true, would they also take part in buying Angelic weapons off the black market or use their own powers to kill angels during the extermination? Or are their powers even strong enough to kill angels? 🤔🤔🤔 (I can always look in my Dad's bible or smth to fact check my theory)
Fun fact - despite appearances, dubious morals, and general presence, I’m also Christian and was raised very conservative Christian. <_< (Obviously, that didn’t take and my version of Christianity is more like all three Abrahamic faiths smashed together, but. ¯\_(ツ)_/¯ ) Regardless, this puts me in the fortunate position of being able to (possibly) answer this!
So, yes indeedy, it is possible for angels to kill natural-born demons. There are ranks in power and ability for both hell-born demons, fallen angels, and current angels, but the long and short of it is “yes... sometimes.)
Many a Christian will tell you no, that angels cannot be killed by demons. However, the description of the first war as well as Revelations argues that yes, they can. Some of them. Possibly.
It’s Christianity, there are no straight answers.
But to separate from religion a bit and focus more on the Hazbin meta of this - because Lord knows Hazbin just grabbed the concepts of Heaven/Hell and Lucifer and then began running -
I’m sure that at least some hell-born demons also take part in the angel weapon black market, if for no other reason than making sure they have a weapon against sinners (*cough*Alastor*cough*triple V*cough*). I’d say that some hell-born demons, like Stolas and the von Eldritches are strong enough to kill an angel - or at least a low ranking one - on their own, though I couldn’t say whether or not it would be a permanent death. Hellhounds and imps, on the other hand, would almost assuredly get their asses kicked.
