Fate is fact.  Every action already made.  How can this be?  Simple.
The thread we exist in, this micro-verse of infinite universes is already played out.
For if it hadn't, if any decision made by anything be different, we would have been in a different micro-verse, a different thread, in which those consequences too had already been laid.
Since that is not our verse and because we share this particular one, everything is already said and done. Being what we are, doing the things we do, is no surprise to the greater picture.
