At the moment we act in response to a problem, each of us sees our approach as justifiable. If we later regret our actions or are called to task, we all have reasons why we should not be blamed or at least not held accountable. We call these reasons “Justifications.” To us, these justifications legitimize our actions. To others who find our actions unwarranted, our reasons seem more like excuses, and our actions unjustified.
Sometimes, we ourselves may be unsure if we are justified in our actions or not because there is a conflict between what our reason and our feelings are telling us. When we see no clear-cut response, we go with the side of ourselves that makes the stronger case.
