Violence is not some sort of terrible magic wand that, no matter how unpleasantly, can always resolve conflicts. In reality, it seldom ever succeeds.
It is a specialised tool that can potentially only work when certain very complex conditions are present; and this requires a tremendous amount of study and analysis.
The misapplication of violence occurs far more frequently than its effective and appropriate use, and the ramifications are vast, and the consequences are irreversible.
