Would you, given the chance go back in time and kill Hitler? Like in 1938 at a big rally? The chances of your survival are minimal but you end up saving millions of people. This comes to my mind as a certain 'Louder then Bombs" contributor wants to dress up as him for halloween.
Is this a morally acceptable thing to do? In both “Harry Potter and the Prisoner of Askaban” and “Back to the future” the characters who are doing the time travelling, (Hermione Granger and Marty Mcfly) respectively are told by the minstry of magic and Doc Brown to not alter the events of time as it may have disastrous consequences for their futures, as we see when Marty begins to disappear when he stops his parents first meeting and chance to fall in love. So what about changing one of the most historically significant events ever?
And if you did it that early on in the period, people wouldn’t have known how bad he was. So in history he would have been considered a great leader for Germany, therefore you would probably be considered in the same way as Lee Harvey Oswald and the guy who killed John Lennon are.
It would still be pretty cool I guess.
