When you lie to someone on a systematic basis, such as with mass political propaganda, you are actually inflicting violence on them, the trauma of which exists as a potential that lies in the psyche, to be unleashed at the time of revelation.
This is because the superego attacks the mind and eventually the entire body when it perceives that the individual is not living in accordance with his or her ideals. This event is painful, and continues to be painful if the individual cannot immediately escape his or her reality. The tension (theorized as cognitive dissonance) is eventually resolved after the person either alters his or her reality (which often takes power) or revises his or her ideals, or at least expectations, to match the new perceived reality. The continued occurrence of this latter possibility results in the exhaustion of the will, a state that is often referred to as "cynicism."
So if you deliberately instill in someone an artificial ideal that is constructed to obscure the underlying reality, there may come a time when that person will correctly apprehend that reality, causing the superego to lash that person, often resulting in internal self-lashings, or an external lashing out at objects, and so the act can only be considered an act of violence.
This act is not always deliberate however, and it is entirely possible that violence is simply inflicted as a reality drifts away from an ideal simply of its own accord.
