"The Road Not Taken" was written in the post-WWI year of 1920, so the idea of choices (and consequences) were very much at the forefront of people's minds...much as they are now. This would mean that there are most definitely socio-cultural considerations at work. The most significant stanza in the poem, in my opinion, speaks to the idea that certain choices are one way roads, so to speak. The speaker in the poem knows that by making one choice, no matter how hopeful he is about possibly reversing or returning to the place where the "paths diverged" is remote, at best:

 "And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back."

Such is the nature of life and an especially poignant idea during wartime. On the site referenced below is a quote by Frost himself, in which he cites the motivation for writing the poem a friend who had joined the war effort.
