Revenge in Martin Scorsese’s Taxi Driver (1976) - Is revenge ever morally justified?

Martin Scorsese’s 1976 film Taxi Driver is widely considered a cinematic masterpiece. Existing scholarly deconstructions focus on prevalent themes of masculinity, violence, and exploitation. This work reinterprets the central narrative as a revenge story in three parts, using cinematic context; the occurrences and actions of the protagonist – the eponymous taxi driver Travis Bickle - to answer the question of whether revenge is ever morally justifiable.
