What is the theme of Shooting an Elephant?

Throughout the essay Orwell explicitly discusses the nature of British imperialism, specifically the way that he, as a police officer, both represents and internalizes the imperial project. He opens by revealing the brutality of British colonialism in Burma, with images of tortured prisoners, and he discusses his distaste for the empire's impact in Burma. He says that he's on the side of the "Burman," yet he also resents Burmese people for the way they perceive him. Orwell's self-consciousness as the face of British imperialism is central to his internal conflict as he tries to uphold the image of the impenetrable empire while going against his personal inclination, and killing an elephant that he doesn't want to kill.
