Final answer:
The mariner won by life-in-death is cursed with immortality, unable to die yet witnessing death, as a consequence for his actions.
Step-by-step explanation:
When the mariner is won by life-in-death, it signifies his entrance into a state of cursed immortality and eternal punishment. He becomes caught in a liminal space between living and dying, witnessing the demise of his fellow crew yet himself unable to find peace in death. This consequence of facing life-in-death reflects the broader themes which often surround the crossing of moral boundaries and the resulting inexorable, often supernatural, justice. The theme of facing supernatural retribution is akin to suffering the consequences of playing with fate, which is also evident in the excerpts provided. The mariner's curse is a reflection of his transgression, and his resulting plight serves as a cautionary tale about the hubris of humanity and the relentless nature of divine or cosmic justice.
