B'wana Beast in “Unfinished Business”

Why was it that for so many heroes, a lifetime battling injustice was born from some tragic loss? Perhaps because for most, the natural reaction to loss is to wallow in one's pain. To let it eat you up. Not for those destined for heroic greatness. Instead, tragedy becomes opportunity to stand up, take stock, and discover what they're really made of. For them it can become... transformative, energizing. And with growth comes wisdom. So the hero can bounce back stronger than before. A champion uncaged, never again to become a prisoner of his demons.
