Avatar Roku warned Sozin that if Sozin did anything to mess with the balance of the four nations, he would have to kill Sozin, as his duty as the Avatar. But then Avatar Roku died because the house he lived in was on a valcano, and the valcanoe erupted killing Roku and his wife. Knowing that the Avatar would reincarnate to the Air Nomads Sozin wiped them out, wanting the Avatar Spirit to stop its cycle. But Avatar Aang was already born and escaped before the Fire Nation wiped them out. So Roku died when the war started. He also blames himself for the war to start, saying that if he acted sooner, the Air Nomads would still be prosperous, and balance would still be in order.
