Lust vs. Chastity - Chastity. While 'Wulf is quite the romantic at heart, he (currently, again his past is a mystery to him for now) isn't one to commit himself, as he is constantly aware of the possibility of his death. While 'Wulf is something of a charmer, it never progresses to anything remotely physical.
Gluttony vs. Temperance - 'Wulf's training at the hands of the Elves has invested him with a very temperate way of life. He seldom drinks, never smokes, and never over-indulges, especially because he seldom has opportunity to, spending so much of his time living rough in the wilderness while travelling.
Greed vs. Charity - Phindor has raised Haelewulf to be a charitable soul, who helps those in need when he can. He seldom has much money, but is always looking to aid a fellow adventurer. His tendency towards "hero mode" has been remarked upon with some amusement by Felaion in particular, especially when beautiful young women are involved.
Sloth vs. Zeal - Well, zeal, because Haelewulf's always ready for scrap. He travels from place to place almost constantly, and trains hard, although his motivations are usually for recognition and to excel.
Wrath vs. Composure - Wrath. There's more of this in 'Wulf's past than he realizes, but it manifests even now as complete ruthlessness and psychopathic tendencies in combat. Likewise, the longer he fights, the more his rage slips from cold fury to outright bloodlust.
Envy vs. Kindness - Neutral. Haelewulf envies Lirandel's fighting prowess, but not to the point where he dislikes Lirandel because of it. He also wishes he was better off financially, but not to the point where he doesn't rejoice in his comrades' good fortune.
Humility vs. Pride - Pride. Haelewulf is proud to the point of arrogance, in both his martial abilities, and his conviction that no one knows better than him. This makes him very resistent to authority, and also somewhat eager to assert his role as "hero."
