We see this happen when he tries to rationalize Polonius' death when he accidentally kills him and ends up coming to the conclusion that it was unexpected to happen. Hamlet seems to see everyone's life differently than the way he sees his own life. When he begins to reason, he becomes someone who believes that God has preserved our future and only he knows how everyone will live their life and how it will end. Hamlet believes that his destiny has always been to avenge his father's murder and make the king suffer as much as his father. Destiny is the reasoning for the difficulties it faces, every difficulty it faces and death tries to rationalize everything that becomes of its own fading. Everyone can live the life they want and set their own goals and do all the things they want, everyone can shape their life the way they would like, even if fate and destiny are considered real. As if you don't always have to live by fate and destiny, sometimes you have to create your own destiny and change what the future holds for anyone. Everyone makes the most of life as they wish, even if they live according to destiny, but some are like villages who believe that no matter what they do, their destiny is already decided and that since they were born their fate or destiny is already decided for them without a way to change what their fate has in store
