At the start of part 2, Gregor overhears his family talking when his father makes the surprising disclosure that some interest has accrued over the past five years on savings put aside from his earnings. While not a fortune, the sum is enough to support the family for a year or two of Gregor's insect state, implying that with breadwinner Gregor unable to work, his father is unwilling to take a job himself.
Despite Gregor's being misled by his father about the amount of Gregor's salary remaining, which has forced Gregor to continue to suffer the torments of his increasingly hapless career, his "enthusiastic" and "pleasurable" reaction to his father's news reveal his characteristic decency and selfless devotion. He takes satisfaction in his father's frugality and in the pride he took in supporting his family, which Gregor recalls as a privilege.
While Gregor realizes that this secret nest-egg would have allowed him to pay off his father's debt and "free himself" from his unappreciated toiling, he feels no resentment towards his parasitic and manipulative father. Gregor seems unable to even consider the fact that his father had been taking advantage of his good nature and hard work and in fact still trusts that it was "better the way his father had done things."
Gregor's virtue and lack of cynicism contrast with the callous and unsympathetic regard of his father, the office manager, and the boarders, and he maintains his psychic, emotional, and moral equilibrium throughout the story until he gives up and dies. Gregor's constant humanity and regard for others while reason and sanity break down around him grounds the otherwise absurd horror in a recognizable, sympathetic human consciousness. This counterpoint provides much of the story's mordant humor and irony in the fact that the now-insect Gregor remains the story's emotional center and displays the only depth of feeling and spirit in the story.
