Man, was I a wreck. He recapitulates it. Hoffman, who strangely lusts after Barnabas, grows jealous of his continuing seduction of Maggie, whom he asks to marry in order to legitimize his need to consumate his desire. All of this seems sudden in the realm of the film and, obviously, the events can play out more languidly on a TV soap but Curtis' approach makes the film more bizarre, more desperate, giving it a nightmarish and disjointed feel - as if making an excursion into a truly sickened mind. After he puts her out, he lurks in the corner of Maggie's bedroom and attacks her, using her blood to regain his false youth.

They know its wrong but they give into the desire everytime. Barnabas himself is aware of his perversion, he even tries to control it but it always overtakes him. These psychological tremors may not have been part of Curtis' agenda but on a subconscious level, they are there.
