So how is it these vamps bad? What have they done that was bad?

Can you tell me what a vampire is? 

A vampire in the classical sense is a creature of myth and legend. A creature that must feed on blood in order to survive. A preternatural creature that has evoked much mystery and horror. The true definition of a vampire is a reanimated corpse that rises from the grave to suck the blood out of living people and thus retains a semblance of life. Not all vampires conform to this definition however. Some are disembodied demonic spirits.. In this vein are the demons of Indian mythology and the lamiae of Greece. These can also appear as a disembodied spirit of a dead person that retains a substantial existence. Others still emerge as a different species of intelligent life. Still others can be normal human beings who have an unusual habit to an odd power. One characteristic shared by all is the need for blood.

You know how to kill them? I do... If they were really vamps there is only one way to kill them. Taking a wooden steak in the heart, a cross, holy water, none of that can hurt a real vamp. How can you hurt and kill the undead?
