I think you have it mixed up slightly. The girls where not dragged along at all. He gave them a choice and they accepted knowing to some degree that what they where doing was wrong. There isn't one girl on board the ship by 12b that was not there through their own choice. Dragged along almost implies that he never really gave them a choice in the matter, when we know full well he did. Everyone but him could have stayed behind, which would have meant he would probably have had no choice but to stay behind too. I am not trying to be scratchy or anything.
