Answer and Explanation:
The use of stanzas by the poet alters the meaning of the poem, as it manages to divide the speaker's thought into blocks, allowing the reader to have access to organized thought and to progressively deepen showing the real personality of the narrator. Without the stanzas we would not have this organization and we could draw wrong conclusions. That's because the first two stanzas can give the impression that the narrator is sorry and unhappy about what he did to people. These first two stanzas are used to explain a speaker's position, but the last stanza is what really shows us what he thinks about it, concluding that he is happy and comfortable with everything he has done.
