It depends on your definition of vampire; either as the re-animated corpse sent to prey upon the living bring pestilence, famine and death in their wake, or the modern interpretation of a person that requires energy/ life-force from another and uses various ways to get it, but is otherwise the same as other people etc......... To my mind it's a question that can be answered in various ways and is entirely subjective of the culture, upbringing etc. of the person answering
