How does the act of killing the elephant in George Orwell's essay "Shooting an Elephant" reflect George Orwell's attitude toward British Imperialism?

HIs attitude is that imperialism destroys both the nation colonized and the colonizer. In the text the man tasked with killing the elephant (for the metaphore, the colonizer) doesn't want to, but every one of the locals expects him to (they're the colonized), so he does and he feels awful about it. This is how Orwell saw imperialism, the white men forcing himself to do things to enforce his rule over others, even when it went against his beliefs.
