Isn't that ironic. The brave kid became a villain, while the coward grew to be a hero. Obviously there's a lot of nuances that happened in their lives, but their origins were practically the same, difference is how they handled it. The brave kid grew with pride and strong ambitions, but grew with such arrogance and cynicism, he dismissed all others and blurred his own perspective. The cowardly child grew more determined and snowballed into greater merits, but forgot his own modesty.
