Violence brings only sorrow into this world, but wrath and indignation, when managed and directed properly, can sometimes generate good and beautiful things.
When one is indignant about the status quo, seeing clearly the defects and shortcomings of the present system, wrath can be the source of a hyperactive creation, resulting in pieces never seen or imagined by humanity.
Wrath is the emotional manifesto of the underdog, dedicated to beauty and truth. When the powers that be stink, get rotten, become unimaginative and oppressive, the wrath of the underprivileged explode and spray fragrance and luminance around.
There is such a thing as the wrath of god. Even the god can be an underdog from time to time. Not to mention us mortals.
