Quote from : Ender's Game Book

There was no doubt now in Ender's mind. There was no help for him. Whatever he faced, now and forever, no on ewould save him from it. Peter might be scum, but Peter had been right, always right; the power to cause pain is the only power that matters, the power to kill and destroy, because if you can't kill then you are always subject to those who can, and nothing and no one will ever save you.
