Well, to understand how Mormons have screwed up Scouting, you need to know how it's supposed to work.
Scouting is first and foremost a voluntary system for boys to learn about the world around them, and their place in it. Camping and the outdoors are the main tools that are used to teach the boy what he needs to know in order to be a good citizen of his community, nation, and world. Proper moral behavior is part of being a good citizen. From day one, the Scout is taught and expected to know the Scout Oath (On my honor, I will do my best to do my duty to God and my country, and to obey the Scout Law. I will help other people at all times, keep myself physically strong, mentally awake, and morally straight), the Scout Law (A Scout is trustworthy, loyal, helpful, friendly, courteous, kind, obedient, thrifty, brave, clean, and reverent.), and the Scout Motto (Do a Good Turn daily).
Leadership (and followership) is also highly valued, and the Scouts should take a lot of time instilling into the boys, formally and informally, the tenets and values of leadership. Boys are given many opportunities to lead in the troop, and a well-functioning troop should be boy-run.
These are just some of my personal thoughts on the subject. The Mormons made Boy Scouting the official program for their boys , and proceeded to turn it into a mandatory Eagle Scout factory.
