Final answer:
Gregor's transformation in "The Metamorphosis" is primarily a metaphorical device rather than an explicitly diagnosed psychological condition, though parallels to Cotard's syndrome can be drawn if one were to interpret his situation as a manifestation of mental illness.
Step-by-step explanation:
In "The Metamorphosis," Ka.f.k.a presents Gregor's transformation into an insect without directly delving into psychological explanations. However, interpreting the narrative through the lens of insanity brings forward parallels with Cotard's syndrome. Gregor's detachment from his human form, his family's rejection, and his isolation within his own home resemble Cotard's symptoms of nihilism and feelings of being dead or non-existent. Yet, Ka.f.k.a's narrative mostly revolves around existential themes rather than clinical insanity. While there are similarities, the text's depth suggests a broader exploration of human existence and alienation rather than a portrayal of a specific psychological disorder.
