What is the issue in the story metamorphosis?

In Franz Kafka's "The Metamorphosis," the central issue revolves around Gregor Samsa's sudden transformation into a giant insect, which leads to profound alienation and isolation from his family and society. This metamorphosis symbolizes the struggle of an individual against dehumanization and the burdens of societal expectations. As Gregor's physical form changes, so too does the family's perception of him, highlighting themes of identity, familial duty, and existential despair. Ultimately, the story explores the fragility of human connections and the consequences of losing one's sense of purpose.
