Answer:
The last stanza is consistent with the others in saying that the grassier, less worn path was the best decision. Also, it follows the others in that the speaker doesn’t dwell on the other possibilities he might have faced if he had chosen the first path. He continues to not regret his decision.
But the speaker seems more certain about his choice here than in some parts of the poem. In other lines, the second path is “perhaps” better, and supposedly less worn, but not necessarily so. Also, earlier in the poem, he talks about keeping the option of returning to the first path and wishing he could travel both. In this last stanza, in contrast, the speaker doesn’t envision sharing with others any of his doubts about the one path being “less traveled by.” He sees himself confidently saying it was a great decision, even though he will never know what would have happened if he’d taken the other path instead.
