Which is an example of a literary theme

For example, a writer may choose a subject of war for his story, and the theme may be his personal opinion that war is a curse for humanity. Usually, it is up to the readers to explore the theme of a literary work by analyzing characters, plot, and other literary devices.

hope this helps :)

In contemporary literary studies, a theme is a central topic a text treats. Themes can be divided into two categories: a work's thematic concept is what readers "think the work is about" and its thematic statement being "what the work says about the subject".
