Unbroken

Why did bullies go after Louie cause he was a thief so you would think he soul get back by stealing something they cared about or somehow like that. And how did his brother turn out all good and louie turn out bad an mischievous? I think since it said he never wanted to go in a plane ever again he will have to fly in the army. It is foreshadowing because it wouldn't have said that if he wasn't.
