Either way it keeps them from the insipid, morally vacuous cult of the anti-hero that seems to permeate modern art. Evil is the new good, dontcha know? I know creative types have to keep looking for new angles, but these stories where the “villains” are all “deeply misunderstood because of traumas in their childhood”, whilst the so-called “good guys” are psychoanalysed into being shallow, prejudiced non thinking types are really going too far.
Anyway, the idea of a teenage girl falling in love with an angst-ridden struggling-for-redemption vampire has already been done (and much better too) in “Buffy the vampire slayer”.
evil is the new good?
have you read the books?
the vampire protagonist and his family don’t drink human blood, they hunt animals and jokingly refer to themselves as vegetarians.
they also have an ongoing dialouge about whether any of their family will go to heaven since they were changed from human to vampire, IOW, does their ‘status’ preclude entry into heaven, regardless of the fact that they were changed involuntarily
one of the protagonist’s objections to changing the female protagonist is that he believes that her soul could never enter heaven even if she never drank human blood or killed a human
and the “father” is an ER doctor at the local hospital, utilizing his abilities to treat patients via heightened senses - almost as pennance for his condition
