The Guardian of the System: Somerset's Role and Perspective

Somerset goes beyond a simple investigator to represent the protagonist in Se7en's central philosophical debate. He is seen to be fixated on the 'rules' and 'procedures' surrounding the case rather than being overwhelmed by its brutality. This shows that he has lived for a long time within the law and system, and his perspective on the case is full of a seasoned quality — cynical yet refusing to let go of essential justice.

1. The Beginning: Building Experience and Skepticism

Early in the film, Somerset maintains a kind of distance from the case as someone nearing retirement. In contrast to the newly assigned Mills's passionate actions, he sometimes shows resistance to taking on the case at all. In this process, Somerset leads from the position of 'assistant' rather than direct participation — for example, finding helpful materials at the library for Mills. This is interpreted as an attitude of keeping guard against being emotionally swayed even while grasping the essence of the case. The film shows the audience only what is necessary to convey the core, and Somerset's observer-like perspective is the basis for evaluation of the film's sophisticated direction.

2. The Key Scene: Upholding Procedural Justice

The moment Somerset's character is most clearly revealed is the collision scene with Mills over entering the killer's residence. When Mills tries to rush to the scene ahead of his emotions, Somerset firmly stops him and emphasizes the legal procedure: 'We need a warrant.' This scene goes beyond a simple warning to symbolize the system of 'rule of law' he believes in. Somerset is standing in the domain that requires legal grounds, not emotional pursuit.

This attitude is consistent with the way the film focuses on the characters rather than violence itself. He takes an intellectual approach even amid the brutality of the crime, probing the human psychology and loopholes of the system.

3. The Philosophical Guide: The Balance of Cynicism and Insight

As events progress, Somerset goes beyond a mere investigator to offer Mills philosophical advice on life attitude and justice. In conversation over drinks at a bar, Somerset says 'I don't want to live in a society where indifference becomes a virtue,' revealing a deep skepticism about the absurdity of the world. This shows that he has tried to realize justice within the system but knows better than anyone the limits and corruption that system itself has.

This insight of his contrasts with Mills's pure passion (idealism), making the audience confront the question 'What is justice?' Somerset continuously reminds us, within the vast labyrinth created by killer John Doe, of the limits of humans who can only move within legal boundaries.

Somerset's Character Arc: The Human Within the System

Somerset's arc shows a subtle change from 'resignation' to 'responsibility.' He begins with resistance and cynicism toward the case as someone nearing retirement, but going through cooperation with Mills and the meticulous traps the killer has set, he feels the responsibility to maintain at least minimal 'order' as part of this system. His existence establishes the identity of the film as not merely a brutal crime thriller but a hard-boiled crime thriller dealing with the tension between the dark desires inherent in humanity and social norms — the core pillar.
