How lusciously evil for Dracula to use "the word of God" as his own during his arrogant rant to Mina, gloating about her husband and friends' failure to find his lair and destroy him while, in their absence he uses his superior stalking skills to gain access to her bedroom and feed from her veins; the one person the men were trying to protect.
Dracula's plan is to use her as a blood supply to punish her for scheming to destroy him, then making her his slave, telepathically linking her to him no matter where in the world she is. He tells her she is now "flesh of my flesh; blood of my blood," a biblical line from Genesis as Eve is created from Adam's rib. Another work of fiction. No matter how repulsed by him, she's helpless to resist. Seems like a bone chilling fate worse than death!
Dracula is so arrogant he believes himself a god or at least possessing the same power and will of a god. He believes he's invincible and confident that he will never be destroyed. That's usually a villain's biggest mistake.
