While, for a time, there was peace, those favoring destruction usually being outnumbered by those who favored one of the others, the balance eventually shifted in the direction of Destruction.
Not that Destruction himself desired it, he wanted the humans to survive after all. It simply was that he let more of his power through in the formation process on accident.
However, this led to the...corruption of the abilities of what was known as the First and Second generation of kwamis, those involved directly with the creation of humanity, whose powers were as much a part of humanity as their hearts or minds.
So, the First and Second generations' powers were corrupted in the hearts of many men. Creation corrupted led men to Cunning, the art of going around the established structure to form webs of people and resources at your disposal. Destruction led to Annihilation, the desire to destroy for the sake of destruction, instead of a way to bring about change. Fortunately for the sake of all, few people ever follow Annihilation, and those who do are rarely followed. Unfortunately, those who do often choose to destroy themselves.
Illusion was twisted to become Deception, the art of hiding a dagger with a smile, of creating masks for the purpose of accomplishing one's goals. One may fail to see the distinction between the two, but Illusion is defined as being necessary and entered to with care, while Deception is a means to an end, a tool of one's own benefit at the cost of others.
Subjection became Tyranny, subjecting others to your will regardless of whether it would be better for them one way or another. Of doing what you desire regardless of the consequences it brings, instead of controlling minimally, bringing true subjection only when necessary.
Protection became Isolation, the idea that the only way to truly defend against any attack is to keep everything, whether attacking or helping, away.
Emotion became Manipulation, using that which others care for as motivation for them to do what you desire.
Transmission became Abuse, as those with anger and pain gave it to others, hurting and causing pain as they had.
The kwamis discussed how to resolve the problem, as no one desired humanity to be destroyed. They did not know what would become of their new brethren, nor whether their power would return. In the end, Creation declared that by humanity came the problem, and by humanity would come the solution.
So, they chose a man who was fully balanced, who saw the virtues of all the attributes, and had some mastery of the abilities given him that most humans never obtain. Using the influence they had, the kwamis brought him to awareness of the troubles of humanity, and what could be done to solve them.
