Which sentence from "Shooting an Elephant" by George Orwell best conveys the author's overall message regarding imperialism?

For at that time I had already made up my mind that imperialism was an evil thing and the sooner I chucked up my job and got out of it the better.

All I knew was that I was stuck between my hatred of the empire I served and my rage against the evil-spirited little beasts who tried to make my job impossible.

Feelings like these are the normal by-product of imperialism; ask any Anglo-Indian official, if you can catch him off duty.

And it was at this moment, as I stood there with the rifle in my hands, that I first grasped the hollowness, the futility of the white man’s dominion in the East.
