The Victorian era, a period when human life changed and transformed, opened the door to a new world for humanity. As life changed with industrialization, people also transformed some of their ideas along with the changes in their mindset. Lifestyles, morals, ideas, and values ​​were affected and transformed in many segments of society by these changes and transformations. Disproportionate shifts in social structure have caused the rich to become richer while the lower classes become poorer. All of this has led to hypocrisy, immorality, and many other negative transformations in society. Developments in morally degenerate societies have had profound repercussions on human life. Oscar Wilde, one of the most important writers of this period, demonstrated the degeneration of humanity and how it can become monstrous in a changing world in his intriguing work, The Picture of Dorian Gray. Therefore, this study will explain how this work, considered gothic, addressed human life and how the deterioration of social structures in a changing and transforming world affected people’s search for meaning and their mindset. It should be noted that the work argues that Dorian’s transformation into a monstrous figure stems from the tension between aesthetic surface and moral interiority, generating a form of horror rooted in psychological and ethical decay. At the heart of the book is the portrait, which functions as a site of externalized abjection: a Gothic mirror that absorbs the consequences of Dorian’s actions, revealing his hidden self as he becomes increasingly grotesque. Starting from this point, the fact that man becomes a monster by succumbing to his inner ambition, endless desire to live and emotions will be discussed and from this point on, the ways in which man has alienated himself, broken away from society and become a monster in today's world will be revealed. Through the examination of Dorian’s portrait, a mechanism emerges that reveals moral collapse and psychological degeneration; this is Dorian’s loss of humanity, even of himself, by revealing the dark side inherent in every human being.
