Destiny and free will

At first your going to ask your self what is destiny and free will , so destiny is the events that will necessarily happen to a particular person or thing in the future that you know , free will is the power of acting without the constraint of necessity or fate ; the ability to act at one's own discretion . There is a big different meaning of each one , like destiny , you know your going to die , that's destiny . free will it comes from it self , that you are free to do what ever you what and you know that if you do something wrong you know that your going to get punished . I believe in both cause life will be nothing without them both .
