| Quote #1 And a good south wind sprung up behind; |
When the Mariner shoots the albatross, the question isn't whether the albatross was bringing the ship good luck, although the poem suggests that it does. The question is: what did the albatross ever do to him? The answer seems to be "nothing," so the Mariner shoots it only because he can. Pride is inherently irrational.
| Quote #2 And I had done an hellish thing, |
The sailors misinterpret why killing the albatross is such a bad thing. They only care about their own self-interest, and as soon as the fog goes away, they are no longer angry with the Mariner. Maybe that's why they get whacked by Death later on.
| Quote #3 I looked to heaven, and tried to pray; |
The "wicked whisper" sounds like the Mariner's pride, which prevents him from doing something so degrading as to ask for help and forgiveness. In this poem, the setting – here, dryness – often mirrors the spiritual condition of the Mariner.
