How does ender react to conflicts? What are his reactions?

Throughout the novel, Ender tries to avoid violence but always ends up getting dragged back in. He originally walks away from the taunting children in the fantasy game, but when they turn into wolves and kill him repeatedly, he must figure out a way to kill them. The computer makes him kill them somewhat gruesomely in order to proceed, and Ender complies rather than give up the game. This pattern is, in some ways, much like the bugger war; in the war, Ender must use violence to kill the buggers, even though he hates to fight.
