A single powerful person who is convinced of their own Rightness with no thought of introspection or means of restraint is dangerous, moreso to others than to themselves. -- Anon Guest
Jack didn't just believe in the Leader. He had a firm and unwavering Belief in the leader. Jack was wont to Believe with all his heart and soul. Though he still prayed to the God of the holy works, the Leader was the next best thing to a foretold coming. The Leader was the greatest man to ever live. The Leader was going to make this nation great. The Leader was going to fix everything.
Jack was so convinced that he convinced his family and friends. Most caught the fever, but some still little-b believed. But that was not a concern because the Leader was now in charge. The Leader was in the best place to fix everything that had gone wrong.
And the Leader certainly got things done.
