What about Gregor”s personality and what can you infer on Gregor?

Gregor Samsa is a traveling salesman, who hates his job but is forced to keep it in order to support his family and pay off his father's debts. Gregor suddenly finds himself transformed into a giant insect. Never coming to terms with his metamorphosis, he struggles with intense feelings of guilt as if his inability to support his family were his own fault. Though freed from his job, Gregor is now a burden to his family and is kept locked in his room. Isolated and neglected, Gregor is a metaphor for the human being oppressed by capitalism and alienated from work, family, and himself.
