the Doctor says as long as you dont interfere and change things time travel is cool....
But, if you change things, when you get back to your time then that's the way things have always been.
So really, nothing has changed and your actions were just part of history.
So maybe ethics don't come into it at all.
and if something important did not happen because of what you did.....like maybe the allies losing WW2 and Hitler ruling the world?....OR something very important in your life....what then?....
But that would be the way that it's always been - it would be the history of the world.
Nothing would actually have been changed for anybody except the person that made the changes.
As I said earlier, how do we know that time hasn't already been tinkered with by someone from the future...maybe a million years into the future?
