2. To develop character and plot: Negative imagery can be used to develop characters and plot lines by showing their struggles, challenges, and conflicts. This can help readers to connect with the characters and to understand their motivations and actions.
3. To reflect real-life experiences: Negative imagery can be used to reflect the realities of life, which include suffering, loss, and tragedy. This can help readers to relate to the characters and the story, and to gain a better understanding of the human condition.
4. To provide contrast and balance: Negative imagery can be used to provide contrast and balance to the positive aspects of a story. This can help to keep the story interesting and engaging, and to prevent it from becoming too one-sided.

However, when used effectively, negative imagery can add depth, complexity, and impact to a literary work.
