What does the theme of interlopers from the quote “there are better things in life than getting the better of a boundary dispute” suggest about how the two men have spent their lives?

"The Interlopers" is a short story written by Saki, the pen name of British writer Hector Hugh Munro. The story centers on two men from rival families. Their hatred for one another blinds them to the important things in life, like life itself.
Georg Znaeym and Ulrich von Gradwitz hate each other with a passion. The origin of this hatred is a generations-long dispute over a piece of land that each of them claims. This dispute over property dates back to their respective grandfathers. One night, the two men decide to settle the argument once and for all through a violent altercation. However, a tree falls on the two men, and they become pinned underneath it.
At first, they are still interested in saving themselves. As the night drags on, however, the two men realize that they will die if they do not cooperate. They also realize that their rivalry was senseless and that “there are better things in life than getting the better of a boundary dispute."
They decide to both call for help, hoping their combined shouting will get the attention of their respective parties. However, their voices attract a pack of wolves instead.
The moral of the story is clear, and the quote above sums it up concisely: some people are so focused on trivial offenses and issues that they don't see the important aspects of life, at least until they face an existential threat.
