I must admit, I like both types of games, depending on my mood. You can create a great game where the main character is a Paladin of extraordinary virtue and an equally great game where the main character is a low-down underhanded no-good scoundrel. Or you can create something where the main character could be either or neither at the player's choice.
Both approaches have a place at the table to me and I wouldn't want to see either vanish. Just as the Fantasy genre in literature has many divisions, all happily taking up shelf space, there is no reason why games cannot do the same.
