“If Hollywood really wanted to discourage torture, fictional torturers would never get the information they want through threats or brutality. Be that as it may, torture has serious drawbacks that go further than prison or the battlefield.”

I don’t think that this is Hollywood purpose, but of making money, like certain papers do in exploiting the “diverse facts” or the “the chronicle of the smashed cats”, the more it is bloody and horrible, the more people are attracted, even in children tales we have monsters, it’s because people like to get scared.
