I get what you are saying, but I think part of the point to Traitor is that Jacen was wrong in his indecision but right to be asking the question. There's not really anything in the novel to motivate Kyp to decide that Jacen is right, and he's not, at least not entirely. Ganner's moment of oneness with the universe is achieved by being himself and acting from his nature. He was primely placed. In order to stop the YV he has to intimidate them, he has to make them afraid to face them, he has to show off and be the badass that he wants to be. He has to be himself. And in just doing what comes naturally, he casts off any sense of Jedi control and let's his passion and joy become guided by the Force within, his innate nature. This is the whole point to the novel. Jacen needs to just be himself. Who is Jacen Solo? Ganner is the demonstration of what Vergere is saying put into practice.
