Skripsi ini bertujuan untuk menganalisis perilaku psikologis tokoh Sweeney Todd yang kepribadiannya didominasi oleh dorongan destruksi. Konflik internal yang ter- represi dalam tokoh Todd dan konflik eksternal hasil interaksinya dengan tokoh- tokoh lain yang memicu dan menjustifikasi dorongan destruksinya tersebut akan dianalisis menggunakan teori-teori psikoanalisis dari Sigmund Freud. Konflik internal tokoh ini adalah kondisi neurosis melankolia yang bercirikan ambivalensi antara rasa cinta yang mendalam terhadap libidinal cathexis dengan agresivitas destruktif yang begitu mendominasi kepribadian. Konflik eksternalnya berupa interaksinya dengan tokoh-tokoh lain yang mempengaruhi mekanisme kepribadian Todd. Dominasi dorongan destruksi yang kuat tersebut harus dilampiaskan dalam bentuk pembalasan dendam kepada tokoh Judge Turpin yang merampas istri dan putri Todd secara paksa. Namun, demi melampiaskan dorongan destruksi dan membalaskan dendamnya, Todd harus menyusun strategi agar misinya terlaksana. Seiring misi pembalasan dendamnya, tokoh Sweeney Todd sang pembunuh berdarah dingin lahir karena dorongan destruksinya yang sudah tidak dapat dibendung.

This thesis aims to analyze the psychological behavior of Sweeney Todd as the main character of the story whose personality is being dominated by a drive of destruction. Using Sigmund Freud's psychoanalytic theories, this thesis would like to discuss the effects of repressed internal conflict in Todd's personality and his external conflict through the interaction with other characters that trigger and justify Todd's drive of destruction. As the main symptom, Todd's neurotic condition of melancholia shows the ambivalence between his inexhaustible love towards his libidinal cathexis and his dominating destructive behavior. Moreover, the interaction with several significant characters really affects his personality mechanisms as another factor that strengthens his destructive drive. Thus, the force of destruction has to be retaliated towards the character Judge Turpin who snatched Todd's wife and daughter away from him. However, in order to retaliate, Todd needs to plan a thoughtful strategy to accomplish his mission. As his mission of revenge goes by, Sweeney Todd's trait as a cold-blooded slaughter is born as a result of the unbearable drive of destruction.
