He lived to find food, provide shelter, eat rubbish, just to survive and protect the species. According to Karen Bernardo's commentary (n.d.), his metamorphosis confronted him with "the greater questions of existence." When Gregor awoke to find himself "transformed in his bed into a horrible vermin" (Kafka, 1), he reacted as if he had to work and fulfill his duty, a surprising attitude, in the circumstances.
Instead of being horrified at the changes in his body, Gregor dealt with it, first as a dream, then just an odd transformation that would not stop him from working and being the same person. He continued to think of ways to get over the problem and get to work, which is a confusing reaction for the reader, as it was a terrifying situation to be in. It was absurd that he continued to think and feel as both beetle and man, but in reality, the person who was Gregor still existed, trapped in that awful body. The metamorphosis gave him time to think and examine his life, the family, and his own place in the world and showed he was still human. When his mother and sister cleared out his room, he felt "they weretaking away everything that was dear to him" (Kafka, 24). He crept out to listen to Grete's music, asking "Was he an animal if music could captivate him so" (Kafka, 33).
