A century of warfare have corrupted the Fire Nation's rich culture, and with it, their firebending-styles were erased from history, being "regressed" into militarized format based on hatred and raw aggression; Zuko and Aang rediscovered firebending in its purest and most harmonious form, "Dancing Dragon Style", from the last surviving dragons. Dragon Style is the bending art first practiced by the Sun Warriors, the earliest incarnation of the modern Fire Nation; for the Sun Warriors, fire is life, energy, and creativity, rather than destruction and hate. And by extension a true firebending master should be able to appreciate the life in all things.
