I wanted to counter with a "what if I am there to kill the other nine Nazis?" but after reading the Wikipedia page for Assassination attempts on Adolf Hitler it seems there's still a >90% chance I would happen to, in fact, be a Nazi.

That page is pretty wild; 2 that stood out to me were the following:

In a last-ditch attempt, Fabian von Schlabrendorff gave a time bomb camouflaged as a package of two liqueur bottles to an officer in Hitler's entourage, as a supposed gift to a friend in Germany. The bomb was supposed to explode on the return flight over Poland. The package was placed in the hold of the aircraft, where it iced up, causing the detonator to fail. Realizing the failure, Schlabrendorff immediately flew to Germany and recovered the package before it was discovered.

As an expert, Gersdorff was to guide Hitler on a tour of the exhibition. Moments after Hitler entered the museum, Gersdorff set off two ten-minute delayed fuses on explosive devices hidden in his coat pockets. His plan was to throw himself around Hitler in a death embrace. A detailed plan for a coup d'état had been worked out and was ready to go but, contrary to expectations, Hitler raced through the museum in less than ten minutes. After Hitler had left the building, Gersdorff was able to defuse the devices in a public bathroom "at the last second". After the attempt, he was transferred back to the Eastern Front, where he managed to evade suspicion.

Imagine the sheer levels of stress these two people went through, starting at the precise moment of realizing their attempt wouldn't work.
