You are an impartial bystander that has no effect on anything or one.
You can only go one direction, if you go back you cannot go forwards, or the other way.
Everything is predetermined, so if you go back and kill someone, it'll turn out that you were supposed to anyway, and even if it hadn't happened in 'your present' you wouldn't know, because it would have happened in your past and you'd just think they had before but now you know who did it.
