Espionage can be driven by sexual conquest rather than material gain.

Evidence

For Danielle Chiesi, a former beauty queen, sexual conquest was the driving force. She extracted confidential information through affairs with corporate insiders. She boasted to Rajaratnam about one of her conquests: “I just got a call from my guy. I played him like a finely tuned piano” (Lattman & Ahmed, 2011). She evidently got more from her conquests than just company secrets: “It is mentally fabulous for me.” — Albert Bandura, Moral Disengagement, 1469
