potentially equal to humans-- that was what they rewarded, not the information Pipo gave that led to that discovery."
"So both of them--"
"The piggies didn't want to kill either Pipo or Libo. In both cases, the crucial achievement belonged to a piggy. The only reason Pipo and Libo died was because they couldn't bring themselves to take a knife and kill a friend."
Miro must have seen the pain in Ender's face, despite his best effort to conceal it. Because it was Ender's bitterness that he answered. "You," said Miro, "you can kill anybody."
"It's a knack I was born with," said Ender.
"You killed Human because you knew it would make him live a new and better life," said Miro. "Yes."
"And me," said Miro.
"Yes," said Ender. "Sending you away is very much like killing you."
"But will I live a new and better life?"
"I don't know. Already you get around better than a tree."
Miro laughed. "So I've got one thing on old Human, don't I-- at least I'm ambulatory. And nobody has to hit me with a stick so I can talk." Then Miro's expression grew sour again. "Of course, now he can have a thousand children."
"Don't count on being celibate all your life," said Ender. "You may be disappointed." "I hope so," said Miro.
And then, after a silence: "Speaker?"
"Call me Ender."
"Ender, did Pipo and Libo die for nothing, then?" Ender understood the real question: Am I also enduring this for nothing?
"There are worse reasons to die," Ender answered, "than to die because you cannot bear to kill." "What about someone," said Miro, "who can't kill, and can't die, and can't live, either?"
"Don't deceive yourself," said Ender. "You'll do all three someday."
