Bitch, blueberry and fox - or why Destiny hates Uchiha and foxes love blueberries
Prologue
Destiny is a bitch.
The only fundamental and truly useful realization in life. Some never get it and some do. These mainly in the moment of an exceedingly painful death. She really does not appreciate someone coming to this realization, for who likes to be called a bitch? Markedly not someone as powerful as destiny. After all she is a personified power who, unseen, steers people`s lives in appropriate directions. Whoever follows her path without reservation will attain wealth, power and glory or a tin of tuna deluxe. According to his priorities, character or goals in life. Or he drops into darkness, loses everything, ends up massacred by an incensed mob or dies of food poisoning after consuming an expired tin of tuna deluxe. Like I said, destiny is a bitch. An extremely fickle one as well. However, there always tend to be people who stand up to their destiny and try to change it. Destiny hates those most of all. You just cannot escape destiny. Fact. You need help from other powers to do this. Unknown fact.
People search for these powers and find them in all possible shapes and varieties. They find power in form of scrolls, Gods of Death, Jutsus, Kekkei Genkai, people with a special Chakra and tins of tuna.
Or in the shape of a huge fox demon with nine tails. But most people rather call on a soul devouring god of death or snatch others Kekkei Genkai or Chakra in order to enhance their own power than to look for a huge fox that is in the habit of gobbling humans neck and crop (and possibly their souls as well).
In fact, nobody with common sense does something so entirely foolish. Madara was not foolish, but he tried to change his destiny. Destiny hated him. He knew she was a bitch. In the end it had to be that way.
