Curse Technique: Death Controlling Possessed Blood

Hidan

Hidan (in general as a whole)

So either two things could be right either hidan is in the right religion because he became immortal by following Jashin or the more likely with how the series is right now Jashin Is an otsutsuki who visited hidan to give him a modified kama seal to make him his next vessel but I doubt any of this would ever happen since hidan is kind of irrelevant in the story currently but that isn't to rule out the possibility of addressing this loose thread

If Hidan got Pain's blood and used Death Possession on him, would he kill Pain seeing as how Pain is already dead?

Im not sure if this is a thing but ive been seeing a lot of stuff about people hating kaguya and i just dont get it, i thought she was a pretty cool villain
