Dracula or Krogstad?

Foster depicts Dracula as “a nasty old man, attractive but evil, violates young women, leaves his mark on them, steals their innocence-and coincidentally their usefulness.” This is parallel to the following scene from A Doll House.
Krogstad. I promised to get you that amount, on certain conditions. Your mind was so taken up with your husband's illness, and you were so anxious to get the money for your journey, that you seem to have paid no attention to the conditions of our bargain. Therefore it will not be amiss if I remind you of them. Now, I promised to get the money on the security of a bond which I drew up.
Nora. Yes, and which I signed.
Krogstad is an older man in whom Nora decided to trust a secret with. He helped her by giving her a loan; however Nora made a mistake that Krogstad spotted. In this scene Krogstad blackmails Nora and tries to get a better position at the bank. This blackmail could also be seen as an older man (Krogstad) stealing a young woman’s (Nora) innocence. Nora innocently tried to save her husband and yet Krogstad is taking advantage of her as Dracula would, according to Foster.
