A wise man told me once:
When you're mad as hell, and just can't take it anymore, grab your rifle and run out to the street corner. If you're the only one there with a rifle, it isn't time yet. Go back inside, and keep a watchful eye.
Cold anger, anon, cold anger. Purposeful action. Definitive action that is towards an end, towards the ultimate goal. Action that is measured and carefully thought through, targeted at the enemy, protective of the innocent.
The goal isn't to just kill the bad guys. The goal is rescue those in slavery, and eliminate the evil at the root. Don't chop off leaves and branches when you have to dig out the roots with a backhoe and dynamite.
