How does this work explore sense and insensitivity?

Insensitivity and perceptions of insensitivity are themes that are repeated throughout As I Lay Dying. Darl makes Jewel go with him on the errand even though he knows their mother will likely die in their absence, just because he needs Jewel’s help loading. Jewel thinks the family is being insensitive to Addie’s death by making her coffin right in front of her. He believes he is the only one in the family who deserves to be with her when she dies.
