The former mill owner was executed for practicing Catholicism, a crime under the law at the time. However, the execution was likely motivated by more than just religious persecution, his wealth and control over the profitable mill made him a target for those who wanted to seize his business. The trial was controversial, and the execution left lasting resentment among his family and supporters.

Foreshadowing: The islanders' fear when discussing the mill's past hints that the execution was not simply a matter of law.

The murders are committed by a living person seeking vengeance for the wrongful execution of the former mill owner. This individual uses the legend of a vengeful ghost to distract from their own identity and motives. The killer methodically targets those they hold responsible for the execution and the subsequent cover-up, though the specific identity is revealed through the investigation.

Foreshadowing: The pattern of killings mirrors the events surrounding the old execution rather than typical ghost behavior.

The islanders blame a ghost because the murdered former mill owner was executed unjustly, and local superstition holds that wronged spirits return to haunt the living. The timing of the murders, seven years after the execution, coincides with the traditional period for ghostly vengeance in Korean folklore. Additionally, the brutal and seemingly impossible nature of the crimes feeds the belief that only a supernatural being could commit them.

Foreshadowing: Early rumors and fear among the villagers set the tone for the supernatural explanation before any evidence emerges.

Wonkyu discovers that the murders are connected to the seven-year-old execution of the former mill owner for Catholicism. He uncovers that the execution was likely motivated by greed for the mill's profits rather than genuine religious persecution. As he digs deeper, he realizes many islanders were complicit in the execution or benefited from it, creating a web of culpability that extends beyond the immediate killer.

Foreshadowing: The investigation's early interviews reveal hesitation and inconsistencies among villagers when discussing the mill's history.

The island's hidden secrets involve the true circumstances of the former mill owner's execution and the subsequent distribution of his wealth and business. Many prominent islanders were either directly involved in the execution or profited from it, and they have kept this hidden to protect their reputations and positions. The paper mill's success was built partly on the unjust seizure of the previous owner's assets.

Foreshadowing: The tension between the wealthy new mill operators and certain poorer residents hints at unresolved grievances.

Wonkyu confronts the unsettling truth that many ordinary people are capable of terrible deeds when driven by greed, fear, or the desire for power. He discovers that the entire island community was complicit in the original injustice, some participated in the execution, others stayed silent, and many benefited from it. This forces him to question whether vengeance is justified and whether justice can ever truly be served when an entire society has committed wrongdoing.

Foreshadowing: The investigator's growing doubt and moral struggle become evident as he learns more about the community's collective guilt.

The ending leaves Wonkyu facing an impossible moral choice: whether to expose the full truth (which would implicate many islanders and destabilize the community) or to allow some secrets to remain buried. The unresolved nature of the conclusion reflects the film's theme that some truths are too dangerous to bring to light, and that justice in a corrupt society is never straightforward. The ambiguity suggests that the consequences of the island's past actions will continue to haunt its future.

Foreshadowing: The final scenes show Wonkyu grappling with the weight of his decision as the truth hangs in the balance.

The former mill owner was executed for practicing Catholicism, which was illegal at the time. However, his execution appears to have been orchestrated by those who wanted control of his profitable paper mill. The charge of Catholicism provided a legal pretext to remove him, allowing others to seize his business and wealth while appearing to uphold the law.

Foreshadowing: Records of the trial suggest the charges were exaggerated and the evidence thin.

Wonkyu doubts the ghost theory because the patterns of the murders reveal human logic rather than supernatural behavior. The killer targets specific individuals rather than striking randomly, uses methods that require planning and knowledge, and seems to be guiding the investigation toward a particular revelation. These factors convince Wonkyu that a living person is using the ghost legend as a cover for calculated revenge.

Foreshadowing: Wonkyu's initial skepticism contrasts with the islanders' widespread fear and belief in the supernatural.
