Who is Captain Loosley from The Wanting Seed and what is their importance?

Captain Loosely is an ambitious but dull servant of the government, who resents Derek's rise to power and works hard to undermine him. He tries to convince Tristram to murder Derek, and when that effort fails, he learns from Derek the whereabouts of Beatrice-Joanna, to take her and the children to government authorities as a way to destroy Derek's reputation. Stupidly, Loosely does not foresee that the upheavals throughout the country and the world will result in new government policies that once again will make heterosexuality praiseworthy, thus defusing the scandal of Derek's fatherhood. His relegation to a low post in the new government seems like a fair outcome of his plotting, since any worse punishment would not be in keeping with a leadership that has repeatedly proven itself to favor sneakiness and self-interest.
