Dude, calm down, bro, you were pretty harsh but you were fair, I just think there should be a measure to this obviously, but not using the context of hedonism for me is turning vampires into too humanized, but I understand your point of view.
Yeah, but that is the deciding thing, vampires aren't human, they are hunters and get their thrills from the hunt or more specifically, from devouring their prey. They get a kick from blood. Nothing else can compare.
So if they start to act hedonistic and normal stuff can't reach the high blood will give you. You either start using blood in ever growing quantities and/or you try to get ever more outlandish impressions to eek some reaction out of your system.
Blood is their addiction and if you are immortal and can't self-destruct via your addiction, you will sooner or later destroy anything around you in the hunt for your next fix. OR others around you will set an end to you for their own protection.
That's why hedonism and vampires never worked for me. If vampires have some rules like the masquerade in place (and lets be honest, vampires would have something like that in place if they don't dominate humans by force) hedonism is the fastest way to break those rules and it gets worse the stronger the vampire becomes. A dead person ¯\_(ツ)_/¯
But that looks completely different if 10, 20 or 50 exsanguinated bodies show up even worse if the Vamp has a type.
Now you have human law enforcement and vampires alike on your heels. No matter how strong a single vamp is if he exposes them all to the world the others will band together and kill him and they need only one good hit, he would have to kill hundreds with more in the wings waiting.
Not sexually, but for power, money and even control? Most of them, I think?
that is pretty sure the exact opposite of hedonism. That is using it as a tool when needed, hedonism on the other hand is not focused.
