Basically the whole exchanging fists can help people understand each other in ways that words can ' t trope They are wasting strength and their injuries will incapacitate them for a certain time . Time that could be spent on their training . In a way this is training for them . Being able to use their full abilities without holding back in a real fighting experience without all the red tape will help them understand their true strength and their true limits . While Bakugou ' s original goal was to fight for glory and to demonstrate his power , right now he just wants to fight Deku with everything he has just to try to wrap his head around what makes Deku better than him .
