I should avoid posting further quotes from random sources, but this gem is such a confirmation of the A.T worldview that it deserves attention. Testimony from a survivor of the Holocaust:
The SS camp commander stood close to the whipping post throughout the flogging. ... His whole face was already red with lascivious excitement. His hands were plunged deep in his trouser pockets, and it was quite clear that he was masturbating throughout. ... On more than thirty occasions, I myself have witnessed SS camp commanders masturbating during floggings."
This is on page 551 of Steven Pinker's The Better Angels of Our Nature, from which you can trace it back to its source.
