Let it fester and boil. So while you toil, it grows. Such should be the nature of anger and vengeance. Those fanciful fantasies that you have. They just waste you. And your thoughts. Do not keep it trapped. Let is run through your veins and be pumped by your heart. Vengeance and anger must consume your mind and soul to manifest in their true form. Otherwise, what you see it just a weak imitation of the true form. The true form is chaos manifest. Those who see it shall tremble and for those whom it is meant, they will perish. Such is the true form of anger and vengeance. Both are similar, neither better than the other or worse off. There is no cost to great for the satisfaction derived from anger and vengeance.
