It does not necessarily, though it is possible. 1. If it is possible to go back in time to kill Hitler, it is possible to go back in time to defend Hitler. There may be a stalemate. 2. We may be living in a timeline that is the result of killing another evil person. Hitler may be an acceptable result of that. 3. We may be at the forefront of time, i.e., there may be no future ahead of us to have already invented the time machine. Similarly, time travel may branch time so create a Hitler-less timeline for copies of ourselves (i.e. no causality.) |
