This exam was obviously more about mental strength than any fighting skills or physical power. The only point was not to surrender. However, rock paper scissors is a fully valid combat of its own, and not even a 50-50 random method (according to some). So, losing it wouldn't have been giving up. It would have been losing honestly. Now Gon obviously won dishonestly and has to live with that fact, burdening him further after the humiliation he suffered at Hisoka's hands in the previous trial.
The only one he would have needed to worry about is Killua. Kurapica and Leorio would be no match for him, and Hisoka probably would have lost interest in Gon the same moment Gon had died. He might still have decided to fight Hanzo at some point, should they have met afterwards, but that goes for anybody he judges interesting enough to fight when he's feeling his bloodlust, regardless of any history.Originally Posted by Uchiha Barles
