Peril of the Starmen

The story follows three alien operatives selected by an oligarchic leadership to learn human language and soothe suspicion while preparing to detonate the planet to release energy needed to preserve their civilization. As indoctrination and information tapes strip their autonomy and feed them cultural facts, one operative, Herb, experiences moral turmoil, resisting orders and grappling with the ethics of sacrificing an entire world. Tension rises between duty, the engineered conditioning intended to make them compliant, and emergent sympathy for the people they have been ordered to destroy, producing a conflict between authoritarian imperative and individual conscience.
