> Doesn't it stand to reason that if it were ever possible to travel back in time and kill Hitler that this would've already happened?

No, because all the idealists who went back in time to kill Hitler (believe me, they were lined up around the block, and with no expectation of a safe return), according to multiple witnesses suddenly and inexplicably vanished just as they were pulling the trigger. Theorists say that outcome may have had something to do with the fact that their own existence depended in some perverse way on Hitler's uninterrupted existence.

All except Martin Bormann, who (I bet you didn't know this) went down into the bunker and killed Hitler and his girlfriend Eva Braun -- and even shot Hitler's dog Blondi -- then made up something about Hitler committing suicide, then disappeared without a trace. Of the top Nazis who survived to the end of the war, most eventually were located, but Bormann totally disappeared.

There's obvious speculation the Bormann was the time traveler we all imagined could have done it, and wished we could be. Too bad he didn't act sooner -- every month that Hitler lived caused the deaths of tens to hundreds of thousands.

Okay, I just made that up. Ordinarily I wouldn't have to say that, but there are so many crazy ideas uncritically embraced these days that I realize someone might take this seriously.
