because destiny is simply the predecided, it is the path in which from birth you are guided... it is the false freedom of being an individual, and all those critical moments... your decisions, they were all set in stone in exact precision... by events out of your control... and all you are doing is playing your role.
destiny does not take sides or provide options... it is the truth of the future to you unseen... it is the script on which exist all the scenes...
because that is the cruel nature of reality... even your individuality... it is no more than a movie... a tape... it is what makes you... your beliefs, feelings, shape.
and you? you are a prewritten character... you are a puppet... so play your role and shut it!
