Ender knew that at this moment he might be able to walk out of the room and end the battle. The way he had escaped from the battleroom after drawing blood. But the battle would only be fought again. Again and again until the will to fight was finished. The only way to end things completely was to hurt Bonzo enough that his fear was stronger than his hate.
In this pivotal moment, Ender realizes he has the option to walk away from the confrontation, reminiscent of how he previously left the battleroom after causing injury. However, he understands that if he chooses this path, the conflict will simply continue to resurface, persisting until one side is completely defeated.
To truly resolve the issue, Ender recognizes that he must inflict enough pain on Bonzo to shift the balance of power—making Bonzo's fear outweigh his hatred. This understanding highlights the complex nature of conflict and the difficult choices Ender faces in his journey.
