Why doesn't Jim want to look at the dead body in the house?

Jim doesn't want to look at the dead body in the house because he feels a deep sense of discomfort and fear associated with death. The sight of the body likely reminds him of his own mortality and the fragility of life, which he finds unsettling. Additionally, he may be grappling with emotional turmoil and guilt, making it even harder for him to confront the reality of the situation. Ultimately, avoiding the body allows him to distance himself from the painful emotions involved.
