While reading The Lord of the Rings novel I do not think that destiny plays a role. I think that every decision that was made was made upon that person because he wanted to. Aragorn made the decison to leave Rivendell himself, if he really wanted to he could have stayed. He left Rivendell to leave his legacy like his family, even if he had stayed he still could've left some sort of legacy.
I don't think that in todays world destiny really does exist. People make there own decision as to what they want and don't want to do.
