How does Kafka treat death in The Metamorphosis?

When Gregor dies, the family grieves momentarily. In their minds, their family member died on the day that he transformed, despite the efforts that Grete made to make him comfortable at home. Much like life with a severe disability, Gregor's condition was one that there was no returning from, and it didn't take long before they reached the limit of their tolerance for his condition. Instead of recognizing that he was still the same son/brother that he had always been, he became the monster in the way. He was a problem that they didn't know how to solve. When his death came, they were briefly saddened. However, they were mostly relieved and glad that he was no longer the anchor around their necks either physically or mentally.
