similar crime to Krogstad's, he was unforgiving with her too. The fact that Nora committed her crime in order to prevent Torvald's death was unimportant to him. Motives do not matter to Torvald. When threatened with blackmail, he goes into a rage that his wife has disgraced him. He has no real loyalty to Nora; she is what might be considered his "trophy wife." There was no instinct, as Nora had hoped, that Torvald would offer to take or share the blame as Nora committed her crime for his sake. Essentially, Torvald's relationship with Krogstad highlights Torvald's inability to forgive and his unwillingness to endure hardship for the sake of love.
Unlike Torvald, Krogstad has the inner strength to admit his mistake, to forego his vengeance, put aside his anger, and make a fresh start.
Clearly, it is Krogstad who is the stronger and, ultimately, more admirable than Torvald. Torvald however, does live in this “perfect” world in his eyes, while the audience believes that Krogstad does not view his life like that because he seeks out revenge on Nora until he finds love which changes his whole perspective about life. In conclusion, both men do have similarities and differences but it is important to understand how Ibsen tried to portray each character for the specific plot that he wrote
out.
