[Kingdoms of Amalur] Whats stopping normal people from defying Fate?

Agarth, for example, claims that he was Fated to be killed by an Ettin, and turned to stew.  He speaks as though this is an inevitable end, until the Fate less One intervened.

What's stopping him from taking his own life?  If he decided to fight in the Arena, would he be unstoppable since none of his opponents would be the Ettin destined to end him?  

If anyone can simply go to a Fateweaver and have an accurate account of their future laid before them, what's actually stopping them from going against it?

The thing about fate is that it is true in part because you are you.  A person who's fate was to die in combat would never choose to take their own life.  Not because the physically can't, but because it isn't in their nature.  In fact, some fates may only come about because the individual knows it is fate and tries to fight it.  When prediction is perfect and accurate like fate, it means that no matter what you choose, it was/is/will be the choice that makes the prediction come true.

Part of your fate is your personality, your choices (past and future) and your place in the world (also past and future).  There is no changing fate.

Think about it this way, Fate is a law of physics.  It's like knowing that red+blue = purple.  No matter how many times you combine dyes, paints and lights, red +blue will make purple.  It doesn't matter what choices you make, those choices will lead you to your fate.  Perfect knowledge of the future isn't very useful because you can't change it.
