HELMER: "I hear [Krogstad] is a good worker, too. But I knew him when we were boys. […] this tactless fellow lays no restraint on himself when other people are present. On the contrary, he thinks it gives him the right to adopt a familiar tone with me." (2.117)
Here's the real reason Helmer is firing Krogstad: once again he's worried about his reputation.

KROGSTAD: "I will tell you. I want to rehabilitate myself, Mrs. Helmer; I want to get on; and in that your husband must help me." (2.283)
It's ironic that Krogstad wants to fix his seedy reputation by blackmailing someone.

MRS. LINDE: "Nils, I have faith in your real character--I can dare anything together with you." (3.58)
Mrs. Linde doesn't care about what people say. She stands out in stark contrast to Torvald and Krogstad, who are obsessed with reputation.
