Good leaders mix objective and subjective impulses. For example, the reason the pilot wants not to crash the plane are subjective (concern for property and life, including his own) but a deep or visceral subjective desire is not enough to prevent him from crashing it, as physics will determine that. He needs objective data regarding its position, speed, and the environment around it.
