hmm, so many replies.

The very definition of destiny dictates that you have no choice in the outcome of your life.
Don't you find the idea of not being able to determine your own life dehumanizing?
I ask you fate people this...
Why would such a thing as fate exist?
To what ends would it serve?
If what we do in life is predetermined, then what is the point to life at all?
The thing that many people misconcieve about destiny is that they think its a grand layed out plan of twists and turns, all done for them. Its not, destiny is a simple undetailed solution. Destiny doesn't make us who we are or makes the decisions in our lives for us, but it does give a vague answer for what will happen to us in the end. The entire idea of destiny is far to "faith" based to ever be truely defined with regulations and identifying descriptions.
Why would such a thing exist? Why wouldn't it? Why does life exist, because of some primordial chemical "accident", because of a "god" being making us and putting us here? How you look at such things is largely determined by what you put more value in, the religious/faith based answers, or the scientific/fact ones.
Sometimes things serve no ends and are simply the result or certain combinations of force and stimuli. To have to give it a definable end to serve is to in fact give it a destiny of its own, which pretty much erases the need for the entire question.
What we do in life isn't predetermined, thats where our free choice and will comes into play. Our destiny, basically our end is determined to an extent, but even then can be influenced by our choices.
By your example much earlier of dying in a plane crash for instance. Destiny doesn't say, "You will die in a plane crash on this date, blah, blah, blah." It will say something more like this "You will die from a fall." This leaves any amount of possibilities as it could be the plane crash, or tripping over your own two feet and cracking you skull on a sidewalk edge. Or perhaps you're a search and rescue member and your rescuing some hikers from a crevas when your support line breaks on your way back up and you die from, well, falling.
All three situations have you dying from a fall, but visibly different as one is just tragic, the second kinda stupid, and the third heroic. It our free will and choices that dictated how we got there and what we were doing when we did get there, but we still fell.

I for one do think life is a game, it more fun to go through that way at least. It just has some very serious consquences. My ideas on destiny are described above of corse and while by no means correct are what I believe, thats all.
Though I will say that destiny from a religious perspective doesn't have to be created, it could just be, just like many beliefs around god or god like figures.
As for god being somewhat diabolic, yes, he/she/it is. Its a christian/catholic belief that god is all good and perfect purity. But the simple fact that if god created the universe and all things in it, then he must have created the evil as well because such a force couldn't exist without him creating it. In order to create it he would have to know and understand it, which means that a part of him is it, which means that god is actually the ultimate bad ass of the universe and probably argues with himself alot.
j/k, its just a theory, a rather goofy one at that.
