Your parents, I'm guessing, are fighting to keep your brother from failing. Despite that, he continues to ruin his life. I'll even go one further, He's doing this because he's been 'helped' along his entire life. If that's true, he knows how empty and hollow his life is. He's searching for a failure that will teach him something meaningful. Hope beyond hope that when he reaches his failure, it does not cost him his life.
