"We should be emotionally prepared for it," Rujit countered. "We would not have survived and become great as a race if we had not conquered all such squeamishness in ourselves. We must be prepared to nullify all opposition by instant drastic action—the most drastic action available to us at any given time."
Rujit paused for an instant to transfix Tall-Thin with an accusing stare. Then he went on quickly, "In an emergency it is often very difficult to decide instantly how necessary an action may be. To take pleasure in killing unnecessarily is therefore a survival attribute of a very high order."
"I would as soon kill the Earth-children as not." Tall-Thin said. "But the slightest emotional unpleasantness militates against survival. Every act we perform must be dictated by reason. Our moral grandeur as a race is based on absolute logic—not on blind instinct. Even in an emergency we are wise enough to determine how necessary an action may be. So your argument falls to pieces."
Tall-Thin straightened, his parchment-dry face crinkling with rage. "This isn't the first time you've questioned my wisdom and authority, Rujit!" he said and his voice was like the hiss of a snake uncoiling in the long grass of a jungle clearing.
Rujit stiffened as if invisible fangs had buried themselves in his flesh. His cheeks could hardly have been called ruddy to begin with but their pallor suddenly became extreme. He took a quick step backward, a look of horror coming into his eyes.
"You wouldn't! No, no, Hilili!"
"The choice is no longer mine alone."
"But I was just thinking out loud!"
Tall-Thin clicked off the beam, leaving Melvin still standing large-eyed and motionless against the wall. He raised the tube which had projected the beam until it was pointing directly at Rujit.
