It is the abuse of the mental force. The abuse can be either systematic and calculated or impulsive and uncontrolled.
This form of violence can be as destructive as physical violence for the victim of it. The only difference there is is that while physical violence is much more visible (in terms of who and when), mental violence is not so easy to detect, so the victim may suffer more prolonged and chronic consequences.
You can get out of this kind of violence just as well as you would out of any other type, but you will have to face greater difficulty in trying to find out WHO and WHEN, which is what mainly makes psychological violence the hardest to eradicate. So many people die without being aware of having suffered it or with the conviction of never having found it out, which makes it impossible to remove its destructive effects.
Psychological violence can lead to death as easily as physical violence. An abused, disorientated, humiliated and disarmed mind not only loses the control of the victim’s life, which makes the victim fall into depression, but it also causes him to lose control of some vital functions, such as glandular and immune functions, to name but a few. His human body will thus be particularly subject to common illness and disease and more prone to develop all the various psychic and psychosomatic pathologies.
Notwithstanding the aforesaid, psychological violence is not yet recognized as a serious crime in western countries.
We hope that a future superior civilization will envisage that these negative and destructive psychological features be given some form of recognition as substantial as the other acts of violence to the human being, under both civil and criminal law.
