Who executed the other executioners?

But then who executed the executioners? Wouldn't they also have to be killed?

I don't think that's entirely true. Legend says his funeral escort killed anyone and anything in their path. https://en.m.wikipedia.org/wiki/Genghis_Khan

They fought till death you guys. And the last one.... was probably one of his sons (who had inherited enough gold for himself and didn't have to rob the tomb, and kept location secret so no one else doesn't get rich enough to overthrow him)

Does anyone else think Genghis Kahn was as bad as Stalin, Hitler, or Leopold II? I know he was an emperor but he seems just as bad those guys.

Plot twist: I killed them all!

so... how do people know this if everyone was killed

"Who shot my horse?"
