The first vampire might have an excuse, but the others? Cure Disease or pray at a temple. Voila, you're no longer an abomination.How is it vampires fault that they were made to drink blood?
Good.Well, if vampires were to have a cure then the race would dissapear from the face of the world. If they prayed all the time then they would never even be known to exist.
If a creature sucks another person's blood, either killing them or turning them into a creature themselves, calling them "murderers" and "abominations" is totally fair.However if they drink other peoples blood they will be known for what they are not abominations, not murders but for what they are, vampires.
