Why do the men not want Lt cross to help them retrieve Kiowa's body?

The men are hesitant to let Lieutenant Jimmy Cross help them retrieve Kiowa's body because they believe it would be too emotionally burdensome for him, as he already feels immense guilt over Kiowa's death. Additionally, they see it as a way to assert their own autonomy and cope with their loss independently, reflecting their desire to handle the trauma without the added pressure of their leader's presence. This dynamic highlights the complexities of leadership and the emotional struggles faced by soldiers in the aftermath of war.
