And worseeven than violence are the motives of hatred, cruelty,revenge and punishment which very often accompanyviolence. Indeed, violence is bad, not intrinsically, butbecause of these motives that go with it.
There can be violence without these motives;there can be violence for a good object as well as foran evil object.
