Elena

Initially in act 1 he will just absolutely whine and bitch every time you try to do something even vaguely altruistic. Under the hood, they're only small dings to your approval--1 here, 5 there; he's constantly annoyed with your average do-gooder player, and it comes off like he's just a purely selfish asshole. Which he is. But there's more to it.

Pay attention to his banter throughout the game and he'll mention how he called on every God, how he wanted someone to rescue him, and no one ever did. How he used to be attracted to heroic princely types like Wyll. It's the bitterness of someone who had his worldview shattered. He's basically in the back of the group rolling his eyes every time you do something cartoonishly heroic, because he doesn't think heroism exists.
