We'd normally expect the female character to be the one whose point of view is more focused on the personal/individual level and the male character to be the one more inclined to be too concerned with principles/the big picture at the expense of the personal.
And in the younger generation, I think we get that more traditional breakdown - Starbuck is loyal to people (to Adama, most of all) and when her loyalty is challenged, it throws her entire being sort of out-of-kilter. Apollo is loyal, first and foremost, to principles (and we saw that the one time he sides with his father, against Roslin, to try and find Starbuck, it's a bit of a disaster). I don't think he takes Roslin's part in KLG2 because he has a personal commitment to her (unlike Billy) - in fact, I think part of the reason he goes along with Adama's coup attempt for so long (instead of, as people have suggested, expressing his misgivings aboard "Galactica" - but would anyone have listened?) is because he thinks, until he SEES Roslin, that Adama might be right. And then once he sees her, he realizes Adama's dead wrong, because she's not crazy or unfit for duty.
