I should like to put it on record that I have never been able to dislike Hitler. Ever since he came to power—till then, like nearly everyone, I had been deceived into thinking that he did not matter—I have reflected that I would certainly kill him if I could get within reach of him, but that I could feel no personal animosity. The fact is that there is something deeply appealing about him. One feels it again when one sees his photographs—and I recommend especially the photograph at the beginning of Hurst and Blackett's edition, which shows Hitler in his early Brownshirt days. It is a pathetic, dog-like face, the face of a man suffering under intolerable wrongs. In a rather more manly way it reproduces the expression of innumerable pictures of Christ crucified, and there is little doubt that that is how Hitler sees himself. The initial, personal cause of his grievance against the universe can only be guessed at; but at any rate the grievance is here. He is the martyr, the victim, Prometheus chained to the rock, the self-sacrificing hero who fights single-handed against impossible odds. If he were killing a mouse he would know how to make it seem like a dragon. One feels, as with Napoleon, that he is fighting against destiny, that he can't win, and yet that he somehow deserves to. The attraction of such a pose is of course enormous; half the films that one sees turn upon some such theme.

Yeah, it's pretty standard for MI5 and MI6. The Met does it too but not on the same level and especially not recently. Orwell was a colonial cop, he likely had first or second hand knowledge of British torture practices. Never put that together before.
