When reading a book, my goal is to read the book. The outcome is known. Do I read it on the can? In bed? On the subway? The route is unknown, but has nothing to do with the goal.
Hang on, why is your goal to read the book necessarily? That is one possible goal, but there are others that could exist. Perhaps you want to expand your vocabulary. Perhaps you want to learn something. Why is "finish this book" the only possible goal.
Thus, I can finish the book, which is one goal of having a book, yet my primary purpose of reading the book isn't simply to finish it. My goal has very little to do with the act of reading the book. My goal is to expand my vocabulary (for example). Thus the end result is entirely known (I will finish the book), and the achievement of my goal is pretty much a foregone conclusion (assuming there is at least one new word in this book).
So, you can certainly know that you will achieve all your goals in reading this book.
Or, if you look at it another way, if you accept that simply resolving a situation in an RPG is not the only goal you can have during play, then event resolution does not have to be unknown in order to achieve a goal during play.
Pawsplay - umm what? What kind of V:TM game do you play where a player will turn to you and say, "Y'know what? I don't like this character, I go for a walk outside" and this is entirely in character and acceptable behaviour at the table?
In any game I've ever played, in any system, offing your own character for no apparent reason is seen as very bad play.
