Did You Die?: After the Mariner describes how everyone on his ship died, the Wedding-Guest interrupts the story with "I fear thee, ancient Mariner!" and has to be reassured that the Mariner did not die.
Disproportionate Retribution: The events of the poem occur because the Mariner kills an albatross. Then again, some critics argue that the albratross is representative of Jesus. Also, nautical folklore holds albratrosses to be good omens (perhaps as they often show land is near) and in killing one it was believed you bring on bad luck and misfortune.
Of course, the fact that everyone on the ship except the Mariner died because of the Albatross slaying not only makes it disproportionate, but misaimed.
Sole Survivor: The Mariner is the only member of his crew to survive.
Space Whale Aesop: "Be compassionate towards all creatures and don't go around murdering innocent seabirds, or else you'll wind up stranded in the middle of the ocean, all your friends will die, their corpses will torment you, and when you eventually make it to land you'll be forced to constantly wander the world telling your story instead of being able to live a normal life."
Ungrateful Bastard: The Mariner shoots the Albatross for completely unexplained reasons, despite the fact that the bird actually just lead them out of the glacial maze.
