@Mithoron actually, I think Sally had an (unnurtured) dark side in the beginning. In Saul, Kim wants to do good in the beginning, genuinely believes in it, and suffers a bit for it, but in Barry, Sally, and others, have their dark side to them, (IOW are normal people) and this is most evident to Barry, which is one reason he sometimes goes mad that these people think they're 'better' than him
