The purpose of torture is torture.
And the population at large needs to be primed to accept torture.
And it is primed to accept torture by the association of sexuality and pain.
In other words the population is primed by sado-masochism.
I saw a movie the other night called, "Taken". It is a sado-masochistic movie distributed to the whole population. And there are other movies as well.
This is effective as we have members here who justify, celebrate and valourise sado-masochism.
Priming us to accept torture.
And I think it was George Orwell who said, "the purpose of torture is torture".
