Describe Orwell's mixed feelings about serving as a police officer in Burma.

From the text:

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. Theoretically--and secretly, of course--I was all for the Burmese and all against their oppressors, the British. As for the job I was doing, I hated it more bitterly than I can perhaps make clear. In a job like that you see the dirty work of Empire at close quarters. The wretched prisoners huddling in the stinking cages of the lock-ups, the grey, cowed faces of the long-term convicts, the scarred buttocks of the men who had been Bogged with bamboos--all these oppressed me with an intolerable sense of guilt. But I could get nothing into perspective. I was young and ill-educated and I had had to think out my problems in the utter silence that is imposed on every Englishman in the East. I did not even know that the British Empire is dying, still less did I know that it is a great deal better than the younger empires that are going to supplant it. 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.
