Wehsal is horrified because he, unlike Settembrini, isn’t committed to Settembrini’s ideals to the degree that he is willing to die for them. The fact that nobody involved in the duel owns a pistol highlights how high tensions have risen at the Berghof: under normal circumstances, none of would be violent, murderous people. Now, they behave as irrationally and haphazardly as Herr Albin. Finally, it’s symbolic that Hans chooses the meadow where he “‘play[s] king’” as the duel’s location. In the meadow, Hans mused over abstract ideals that he could never translate into lived experience. In suggesting that the duel take place in this place, then, he is conveying his hope that the duel will not result in any real, physical consequences—that both men will escape alive.
