Definition: Information, especially of biased or misleading nature, used to promote or publicize a particular cause or point of view.
The event of September 11, 2001 relates to the book V for Vendetta because they both have propaganda, and someone responsible for “terrorism”.
In V for Vendetta there was a controlling government that sheltered the people from the world, and only exposed them to what they wanted them to be around. Propaganda occurs when it comes to the characters V and Evey Hammond.
V noticed there was more than just being sheltered physically, it was a mentality also. To make Evey feel free inside and out V took it upon himself by making her feel under pressure, alone, and stripped of everything.
When it came to the murders of people who were affiliated with Larkhill Evey thought it was wrong, but once she saw V’s point of view and that he was a victim victimizing others she understood why he was carrying out the attacks.
