Here's how the poem explores this theme:
* Loss and Trauma: The poem focuses on the physical and psychological scars left by war. The speaker describes a "casualty," a soldier who has lost limbs and is haunted by the horrors of the battlefield. The imagery of "empty sleeves" and "blind eyes" highlights the devastating effects of war on the human body and mind.
* The Burden of Memory: The poem suggests that even after the war ends, the memories of violence and loss continue to haunt those who have experienced it. The speaker describes the "haunting shadows" that follow the soldier, representing the psychological trauma he carries.
* The Responsibility of Society: The poem also implies a responsibility on the part of society to care for and remember the victims of war. The speaker asks, "Who will bear the burden of this loss?" This question suggests that the scars of war are not just individual burdens but also a collective responsibility.
Overall, "Casualty" is a powerful reminder of the profound impact that war has on human lives and the importance of remembering and honoring those who have suffered as a result. It emphasizes that war is not just a historical event but a lasting reality that continues to shape individuals and communities long after the fighting has ceased.
