Van and Folken form opposite sides, though their intentions are equally noble. It is Folken's willingness to exploit others to achieve his end that separates the two brothers and what ultimately makes him wrong.

Van desires peace as much as any king, or really more specifically, any person. He hates to see people suffering, and that is always the cost of war. Although his training is incomplete and he is mostly inexperienced, Van fights valiantly for the sake of those people, willing to sacrifice himself, but not those around him.

Folken is also willing to sacrifice himself, but he is also willing to do the same to others. Certainly he doesn't like to see people killed, and he knows that their deaths being for the greater good provides no consolation for their loved ones, but still he allows and even facilitates in the destruction. He considers the willingness to have bloodstained hands for the sake of the greater good noble. Van does not.

Folken insists that they must fight for the sake of peace, and Van replies that there is no such thing. Who is right? Mostly Van because it is impossible to force people to want peace, or really, to want anything. The best you can do is deal with those who would sacrifice others for their own good as they come along, because force is only excusable and necessary when used in defense. Will wars still happen? Possibly but becoming immoral yourself only allows those who would use force to use you as well. Evil cannot be fought with evil because no body can win in such a battle. People must choose peace, and that can be a difficult choice to make.

All through this, Folken seems to still love his brother unlike any other. He wants him out of the way and he certainly messes with his life, but he never wants him dead. He wants him at his side. He wants him to share his vision of a peaceful Gaea. His desire to bring peace to the land is rooted in his longing to create a world were kindhearted people like his dear brother would not suffer and could be happy. He most likely marvels at his brother's ability to oppose him and his best laid plans. He wants his brother alive to enjoy the world he will create, but his interference might destroy the dream.

Van has always loved his brother and defended his honor. Finding his brother on the opposing side was a terrible shock. Not only was there the matter of honor, but he probably felt hurt and abandoned by the hero he had loved and admired. He was angry and hurt, and he probably did hate his brother, but even than, in the back of his heart, he still loved him. Still there is nothing more heartbreaking than the fall of a hero. Van does not suggest that he will turn his brother to his side as he seems dead set against him. Maybe he never considered that a possibility. That makes it particularly hard for him to believe Folken when he comes to his side.

Even war cannot break the bond between the brothers, but it certainly strains it. The brothers' philosophies put them on opposite sides, but that doesn't mean that they can never be together again.
