Common Theme

I think that the theme shared between "The Final Salute" and "Do Not Go Gentle Into That Good Night" is that it is never easy to accept a loved one's death. I believe that that is the common theme because in the article, it mentions how Sgt. Cathey's wife and best friend dealt with his death. His wife was left alone with her unborn son, with no one there to help her up in her time of sorrow. In the poem, the poet is telling his father not give up his life to death. Even though his father has already accepted his death, the poet still wants him to fight it because he doesn't want to accept his very near future.
