he's a vampire though, correct?

Well technically he's a demon who drinks human blood. He's similar to a vampire. Also he gets his blood from places like blood banks so he doesn't have to kill for that reason. He just believes that evil people should be purged from the world. For that reason he destroyed and killed every member of the human organization that raised him.
