Yes. It's-- in my world, vampirism is a choice, a choice that is made every day. They are not reliant on blood to survive; they are reliant on blood to be immortal. It may sound like a small distinction, but it is the reason why people continue to die at their hands - not because our vampires fear starvation, but because they become more or less human once more should they stop killing.
I should be a better person and understand the distinction between what they are and what you are. I am sorry. I am trying.
