I think you all have this album all wrong. All of Pink's suffering is self-inflicted. He's building the wall around himself and attempting to justify all of the wrongdoings he has committed in his life by doing so. The Nazi sequence is a bout of insanity caused by the drugs given to Pink in Comfortably Numb to "keep him going for the show". He uses this as a chance to become a dictator to his fans... to make himself feel more important and powerful.
