An Analysis of the Split Personality of Nonoguchi Shu in <i>Akui</i> Based on Lacan’s Psychoanalytic Theory

文章基于拉康精神分析理论，结合黑暗三联征人格模型，分析东野圭吾著作《恶意》中野野口修的主体分裂人格。研究指出，野野口修的恶意源于童年创伤导致的镜像阶段认知断裂，以及象征界秩序下主体性的崩解，其人格特质契合黑暗三联征特征。文章提出“穿越幻想”是抵御人格异化的可能路径，强调直面现实、重构主体与他者关系的重要性。研究不仅解读了《恶意》中的人性暗面，也为理解极端人格成因提供了理论视角。This study employs Lacanian psychoanalytic theory and the dark triad personality model to analyze the subjective split personality of Nonoguchi Shu, the protagonist in Higashino Keigo’s Akui. It argues that Nonoguchi Shu’s malicious behavior stems from a cognitive rupture in the mirror stage caused by childhood trauma and the disintegration of subjectivity within the symbolic order, with his personality traits aligning closely with the Dark Triad characteristics—narcissism, Machiavellianism, and psychopathy. This study proposes that “traversing fantasy” may be a way to resist personality alienation, stressing the importance of facing reality and reconfiguring the subject—other relationship. Overall, this study not only interprets the dark side of human nature in Akui but also offers a theoretical perspective for understanding the origins of extreme personality.
