I prefer to think of it with Revan as male, starting off neutral but becoming more lightside as time goes by (particularly after the Jedi training), then with the revelation... Bam! Anger and betrayal right into a major darkside leaning. So, DS at the end, but I hate to pigeonhole it like that. And I see the Exile as female with a strong lightside bent, but not bowing and scraping to the council and not above outbursts of anger. Which leads towards the end of the game to some serious flirting with the darkside, but she does the right thing at the end.
That's the way I like to think of it anyway, heh
