I get it. and I agree with you that he had no role in Nazis deaths
Nazis died because they were not worthy of opening the Arc or maybe no one was and Indiana didnt do anything about it but still that in my opinion is not a flaw
I do disagree about Nazis finding the Ark without his help. he had the medallion and he used it to trace the whereabouts of the arc
he did play very important role throughout the story. he solved the puzzles and extracted the ark right under their nose. agreed they snatched it off him but he was the one who found it and also brought it back to be stored away from the world forever by "top men"
I will check the big bang video and come back on that too.

I saw the big banng video and saw the argument by the geek girl. I disagree with her. the Gashtapu failed to get the medallion from the girl. that was the key to the Ark .. it was Indy who got hold of it . used it and extracted the ark.
yes Nazis were meticulous and very excavating the entire place and might have found it but its a would have could have should have argument.
what is debatable is the dialogue between the German professor and Indy at the end of the movie where Indy is about to blow up the ark with an RPG and the German implores him to join him and find out what the Ark holds by touching his archaeologist curiosity. the Germans might have just executed him or being a persistent pest but they didnt. (again could have should have would have). then again he would have just hid back and let them die and then picked up the ark but that would've been out of his character.
another (disappointing) bit is that the American authorities were not willing to tell him what they did with the ark. he was just hushed up
my 2 cents
