He put away the rage, though. He locked it up. He decided that he would be a more effective tool of punishment if he did not speak the rage inside him, did not attempt to describe it, to verbalize the rage itself. Bin Laden never ranted or raved as other men of great violence do. The speeches of Adolf Hitler are always a touching point. Hitler would whip himself into a frenzy as he spoke, driving himself into heights of outrage that spilled over and into the audience. The point was to unleash those demons of violence in himself and therefore let everyone listening know that they, too, could unleash those demons. Hitler wanted to sculpt a German public that was comfortable with the angry and dark passions of violence. He wanted them to feel that rage was appropriate and that the actions resulting from rage were the natural next step. Hitler never found it difficult to express his rage. He gloried in expressing it. He lived to express it. He became one of the acknowledged masters of expressing rage.
Osama bin Laden went the opposite route. His was the calm and deliberate side of violence.
