"I'm not talking about fame, Ender. I'm not talking about power, either. I'm talking about accidents, just like the accident that Mazer Rackham happened to be the one who was there when somebody had to stop the buggers."
"If I'm here," said Ender, "then I won't be there. Somebody else will. Let them have the accident."
His tone of weary unconcern infuriated her. "I'm talking about my life, you self-centered little bastard." If her words bothered him, he didn't show it. Just lay there, eyes closed. "When you were little and Peter tortured you, it's a good thing I didn't lie back and wait for Mom and Dad to save you. They never understood how dangerous Peter was. I knew you had the monitor, but I didn't wait for them, either. Do you know what Peter used to do to me because I stopped him from hurting you?"
"Shut up," Ender whispered.
Because she saw that his chest was trembling, because she knew that she had indeed hurt him, because she knew that just like Peter, she had found his weakest place and stabbed him there, she fell silent.
"I can't beat them," Ender said softly, "I'll be out there like Mazer Rackham one day, and everybody will be depending on me, and I won't be able to do it."
"If you can't, Ender, then nobody could. If you can't beat them, then they deserve to win because they're stronger and better than us. It won't be your fault."
"Tell it to the dead."
"If not you, then who?"
"Anybody."
"Nobody, Ender. I'll tell you something. If you try and lose then it isn't your fault. But if you don't try and we lose, then it's all your fault. You killed us all."
"I'm a killer no matter what."
"What else should you be? Human beings didn't evolve brains in order to lie around on lakes. Killing's the first thing we learned. And a good thing we did, or we'd be dead, and the tigers would own the earth."
"I could never beat Peter. No matter what I said or did. I never could." So it came back to Peter. "He was years older than you. And stronger."
