: Thanks man, I was aiming for both emotions. Before posting this piece I should’ve clarified this question; “Exactly what is it the characters regret”? He repents because of his decisions (line 15 and 16 shows an example, but doesn't go into much detail...) Eventually regret turns into despair following his final judgment, instead of trying to fix what he did wrong; he accepts his fate. I hope this clarifies the poem a lot more.
: Thanks man! I’ll do that.
