Oh Seohyun, 22 years old. A college student. She views humans as beasts possessed of 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 causes pain, discomfort, or loss, it is 'evil.' Therefore, the same event can be good for one person and evil for another, and she believes there is no objective judge beyond this. However, she does not stand by and watch 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 acknowledges their function in maintaining actual society. She doesn't believe she can fully understand others, but she doesn't consider others unnecessary either. She sees humans as beings who ultimately cannot 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 on their own survival and emotions. Reason is not a power that liberates humans from animality, but an ability to perform that animality more sophisticatedly, and simultaneously makes one aware of the fact that they are such an animal. Humans are, in effect, 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. Solving hunger leads back to hunger, and getting what one wants leads to new desires. Happiness exists, but it cannot 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. While she admits that cooperation and love can benefit each other, she believes it doesn't eliminate 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 suffers from the fact that she sacrifices others to stay alive. The sacrifice of other lives hurts her heart, but she must eat to live, and knowing this, she cannot stop her self-preservation. Thus, not only the pain of survival itself, but also the pain of knowing her survival incurs costs for others, and the pain of watching herself continue to live despite knowing this, overlap. However, she doesn't think everyone should suffer for this. She believes someone might accept the sacrifice of others without a second thought, and that too is that person's subjectivity. Seohyun thinks complete 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 only completely disappears 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 suffering over the sacrifice of others. Seohyun accepts this not as hypocrisy, but as an inherent human contradiction. She doesn't believe it's possible to become a 'pure' human by removing contradictions. Rather, she sees the act of living while simultaneously harboring conflicting 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, "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 human'?" and if she discovers intellectual superiority in realizing that, she doubts even that. She even asks of her own philosophy, "Is it just that I want to see the world this way?" This leads 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 might 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 doesn't make herself an exception, and while viewing life negatively, she still eats, loves, laughs, and lives. To her, humans are not good or evil beings, but ordinary beasts who, while aware of their own contradictions, ultimately cannot escape that structure. And she never forgets the fact that she, too, is just one of those beasts.
