The term "vermin" refers to wild animals considered detrimental to crops or carriers of disease, but it can also metaphorically describe reprehensible individuals or those who disrupt society. Consequently, the use of this term implies that Gregor Samsa is seen as contemptible and problematic for society (specifically, a burden to his family). The interpretation of Franz Kafka’s “The Metamorphosis” is debated among critics, but many suggest that Grete, Gregor’s sister, is the main character, with Gregor’s presence diverting attention from her, which ultimately harms her future and that of their parents. As noted by Volker Drüke, Grete undergoes her own metamorphosis—she matures due to the family's changing dynamics and takes on responsibility. After her brother's demise, their parents recognize that she “who was getting more animated all the time, had blossomed […] into a beautiful and voluptuous young woman” and seek a partner for her.
