Rage and Wrath
All rage is a call to deconstruct a perceived problem into a simpler form so it can be solved at a level on which it can be understood. Doing this in a social manner is difficult because social elements do not have easy direct representations.
Anger is a desire to reduce a thing so that it can be dealt with simply. But it is also possible to increase your own understanding of a thing so you can deal with it on a current level.
This is the cause of most violence.
