Well, it might not matter.
There's some very strange things going on in quantum mechanics.
I won't go into detail but, the double slit experiment seems to show that all possible outcomes occur until one is observed. So, at least for the observer, and what ever is involved in that sequence of events... that's reality.
They call it the double slit experiment, because it was originally done with just 2 slits, but the results are the same regardless of the number of slits.
That leaves us with.... who's doing the observing, and which sequence of events have they chosen to observe? Meaning, if we traveled back in time and killed Hitler before he took power, would it really change anything? That sequence of events is just one of an infinite number of possibilities, and if it's not the one being observed, it's not the reality of the observer, nor those being observed.
It could also be that every possibility does occur within a separate time line. So, if you travel back in time and kill Hitler, you have entered, or created a distinctly separate time line. That time line would progress without Hitler, while the one you left may continue the way it was when you left.
If either of these scenarios are correct, time travel would have little, if any consequence.
So, I don't know.... I guess I might go back and kick the crap out of Hitler, just to get it out of my system.
