This study examines Fyodor Dostoevsky's understanding of freedom, crime, punishment, and social existence within the broader framework of existential philosophy and contemporary human experience. The study argues that Dostoevsky does not present freedom as a simple condition of autonomy or liberation but as a deeply complex and burdensome reality capable of producing both moral elevation and existential destruction. Drawing primarily from Notes from Underground, Crime and Punishment, and The Brothers Karamazov, the paper explores how Dostoevsky portrays human beings as fundamentally contradictory creatures who desire freedom while simultaneously fearing the responsibility and uncertainty that accompany it. The study further examines how freedom, when detached from ethical responsibility and spiritual consciousness, degenerates into rebellion, alienation, nihilism, psychological fragmentation, and self-destruction. Using a philosophical and interpretive analytical approach, the study engages major scholarly perspectives from thinkers such as Joseph Frank, Nikolai Berdyaev, Mikhail Bakhtin, and Jean-Paul Sartre to evaluate Dostoevsky's contribution to existential thought. The analysis demonstrates that crime in Dostoevsky's philosophy extends beyond legal violation and becomes a form of metaphysical rebellion against moral truth and communal existence. Likewise, punishment is interpreted not merely as external legal judgment but as an internal experience of guilt, anxiety, spiritual collapse, and psychological disintegration. The study also argues that Dostoevsky rejects radical individualism by emphasising social existence as a moral relationship grounded in compassion, responsibility, and human interconnectedness. The paper concludes that Dostoevsky's philosophy remains highly relevant to contemporary society because it illuminates modern crises of alienation, moral uncertainty, social fragmentation, and existential anxiety. Ultimately, the study maintains that authentic freedom, in Dostoevsky's vision, can only exist when joined with ethical accountability, spiritual awareness, and meaningful human connection.
