"I can't help being a gorgeous fiend,
that's just the card I drew"  -Lestat

"It seemed as if the whole awful creature were simply gorged with blood, he lay like a filthy leech, exhausted with his repletion".
Jonathan Harker  'Dracula'
The vampire archetype has always been dual-faced.  In variations in a theme, they manifest as the seducer or the predator, spanning the animalistic and terrifying to the desirable and magical.  Recent trends have been towards presenting the vampire less as an evil figure and more as a complicated, ambiguous one.  Be as it may, so long as the human race exists, vampires will be found lingering in the shadowed places in the collective mind where Eros and Thanatos play Truth or Dare.
