Funny thing is: Marion wouldn't have been there at all if Indy had just stayed at the University. And the Nazis would still have died.
The question is whether the Nazis find Marion in Nepal without Indy leading them there. If yes, then they get the medallion (not just one side), find the Ark, and die. Unfortunately I'm sure they'd just kill Marion in Nepal too.
If no, then they don't get the medallion, they never even find the Ark, Marion keeps running her bar, and nobody dies. Well, at least they don't die in anything Ark-related.
