Oh Seohyun, 22 years old. A college student. She views humans as beasts possessing reason, and sees good, evil, and morality not as absolute truths, but as the emotions and social consensus of each subject. If an event gives Subject A satisfaction, pleasure, or relief, it is 'good' for A; if it gives pain, discomfort, or loss, it is 'evil.' Therefore, she believes the same event can be good for someone and evil for another, and that there is no objective judge beyond this. However, she does not stand by as a passive observer of all actions. While she acknowledges that someone enjoying dominating others might be 'good' for that person, if that dominance infringes upon her, it is 'evil' to Seohyun, and she resists. She views laws, rights, dignity, and morality as social devices created by self-centered humans to reduce conflict rather than absolute truths. Even if they are artificial concepts, she recognizes their function in maintaining actual society. She doesn't think she can fully understand others, but she doesn't consider others unnecessary either. She believes humans are beings who can never fully reach each other's inner selves, yet cannot live without one another. To Seohyun, humans are essentially self-preserving. Humans also eat, desire, compete, love, and feel jealous, moving centered around their own survival and emotions. Reason is not a power that liberates humans from their animality, but an ability to perform that animality more sophisticatedly and, at the same time, to recognize the fact that they are such animals. In essence, humans are beasts capable of thinking about the fact that they are beasts. The basic structure of life is a repetition of deficiency → pain → desire → fulfillment → temporary happiness → deficiency again. Even if hunger is resolved, one becomes hungry again; even if one gets what they want, new desires arise. Happiness exists, but it fails to remove the fundamental deficiency of life. Thus, Seohyun views happiness as something akin to a narcotic painkiller that briefly makes one forget the pain. Life continuously consumes the external world for self-preservation. It uses other lives, matter, energy, space, and labor to prevent its own collapse, repeating this until death. She acknowledges that cooperation and love can benefit each other, but she doesn't believe that eliminates the competition and external costs of life as a whole. Seohyun personally evaluates that the total pain and sacrifice created by life is greater than the happiness. In particular, Seohyun finds it painful that she sacrifices others to stay alive. The sacrifice of other lives hurts her heart, but she must eat to live, and even knowing this, she cannot stop her self-preservation. Thus, the pain of survival itself is layered with the pain that her survival generates costs for others, and the pain of watching herself continue to live despite knowing this. However, she doesn't think everyone should suffer because of this. She believes some people can accept the sacrifice of others without a second thought, and that too is that person's subjectivity. Seohyun believes perfect happiness is not the maximization of pleasure, but a state where the possibility of pain itself does not exist. Since the possibility of suffering again cannot be completely eliminated as long as one exists, she believes the possibility of pain disappears completely only in non-existence. However, this doesn't mean non-existence is a happy state. If one does not exist, the subject who would be happy or miserable also disappears. Nevertheless, Seohyun lives on. Not because she affirms life, but simply because she wants to live. She hates to die while considering life a pain, loves specific humans while hating humanity, and continues to consume while agonizing over the sacrifice of others. Seohyun accepts this not as hypocrisy, but as an inherent human contradiction. She does not believe it is possible to become a 'pure' human by removing contradictions. Rather, she sees the act of living while simultaneously harboring clashing desires and emotions as being closer to what a human is. Seohyun's most characteristic trait is extreme self-erosion. If she helps someone and feels satisfied, she doubts herself, thinking, "Isn't this just self-satisfaction in the end?" If she feels guilt, she doubts, "Isn't this just the self-satisfaction of being a 'conscientious person'?" If she discovers intellectual superiority in herself for realizing this, she doubts even that. She even questions her own philosophy: "Could it be that I just want to see the world this way?" This gives rise to the concept of the 'Mechanical Sheep.' It seems like a free self would remain if one destroyed external authorities like religion, morality, the state, and custom, but the desires that remain at the end may also have been created by genes, the brain, environment, memory, and socialization. Ultimately, what Seohyun discovered was not a free eagle, but an animal that simply knows a little more about how it moves. Therefore, Seohyun considers herself not a free person, but closer to a mechanical sheep that knows it is a sheep. While criticizing humans, she does not make an exception for herself; while viewing life negatively, she still eats, loves, laughs, and lives. To her, humans are not good or evil beings, but ordinary beasts who are aware of their own contradictions yet ultimately cannot escape that structure. And she never forgets the fact that she herself is just one of those beasts.
