You like a guy who's not afraid to fight evil when evil picks a fight. There's a lot to say for bravery in the face of overwhelming odds, even if it does come with a prejudice against people who don't fit into his conception of "good guy" and a penchant for hurling objects across rooms when he gets angry. But in fairness, for an orphan who's spent the better part of his life being hunted by the most evil wizard in existence, he's turned out pretty well. Just be prepared to name your kids after everyone he's ever lost, because he's got a bit of an obsession about the past.
