If you were to travel in time, would you be able to change the future with your actions?
Yes: Going back in time could alter the timeline and set you on a whole new one. Certain people that are very important could be killed, then they wouldn't shape the future. No: any actions in the past would have already altered the future so therefore, you can't change anything. It already is set and what you do to change it could be the thing that sets it into motion. I personally lean more towards yes, because I like to believe you can shape your own future and everything you do matters.
