So the general cultural expectation of Dracula's turn of the 20th century audience is "I die, I'm a good person, so I'm going to heaven for eternal bliss."

Now here comes Dracula, an entity that entirely breaks the universal system.

If he bites/enthralls you, you can't die. If you can't die, you are never able to go to heaven. You are sentenced to this weird undocumented middle ground, forever stuck in mortal torment. That must have been so shocking at the time!

A second way it breaks the system is suddenly your actions don't matter anymore for eternal life. There is a creature that overrules the rules. You can be good (saved) and in the book of life, but if Dracula gets you, you are eternally lost and cursed. Not only that, but he can command you to go out and enslave others: those you know and love or strangers. It's reverse evangelism where Dracula and his followers are spreading damnation.

I can't think of a more horrific situation than to have eternal life and suddenly lose it through a creature's attack. Talk about dramatic jeopardy! It doesn't get any higher than a creature that steals your mind and eternal soul!

My point of looking more deeply into the original vampire is to show how thoughtful and culturally shocking it was. The Dracula novel is patient and brooding, not violence, gore, or eroticism. Dracula has to operate under some specific rules and the protagonists need to figure out what they are to defeat him. There is very little violence in the book, I recall only a pistol and a stake near the very end. I'll never forget the evening spent in a cave surrounded by a circle of sand keep Dracula's minions at bay, waiting for the morning light. That was epic drama!

I'm a little less versed in werewolves than vampires. Though I have read the entire White Wolf Werewolf: The Apocalypse RPG rule book.
