question:  Which of these is not true about Harrel Critten?
context: Sure I'm a Nilly, and I've died seven times, always in the blackness of the outer reaches, and I'm not alone, although there aren't very many of us, never were. Interstellar Chief Rexroad knocked the dottle from his pipe in a tray, saying, "Transworld Press is willing to let you have a leave of abscence, if you're interested." The Weblor I had taken off on the first trip to Antheon five years before with a thousand families, reached the planet with less than five hundred surviving colonists. The decision of Interstellar was that the colonists started a revolution far out in space, that it was fanned by the ignorance of Captain Sessions in dealing with such matters. "We have conquered the problem of small groups in space—witness the discovery of Antheon, for example—but when there are large groups, control is more difficult." It ended with passengers engaging in open warfare with each other and the crew. "As I recall," Ellason said, "there was something about stunners." We don't think anything is going to happen, but if it does, we want to get an impersonal, unprejudiced view. Being a Nilly is important, probably as important as running the ship, and I think it is this thought that keeps us satisfied, willing to be what we are. The Weblor II had been built in space, as had its predecessor, the Weblor I , at a tremendous cost. In Ellason's mind the incident, though insignificant from the standpoint of the ship as a whole, could very well be the cause of dissension later on. He said it was significant that all en route had passed stability tests, and that it was to the ship's discredit that someone with criminal tendencies should have been permitted aboard. What did Captain Branson think of those colonists who killed each other on the Weblor I ? But the point is, we know all this, and knowing it, we shouldn't let it happen.
