Anger is an emotion or a passion that is part of our life as human beings. Jesus speaks out strongly against giving this emotion free reign in our lives however. He wants us to see that if anger goes unchecked, it will inevitably lead to murder. We can certainly distinguish between our thoughts and our actions, but the starting place of all human action is reason. When reason takes its cues from anger, the resulting action is a violent rectification. We must learn to distinguish between what needs to be corrected because it is unjust or untrue, and what we would simply like to change because it goes against our own ideas or perspectives.
