You return home after working with the government to hunt down your old gang. They come back to finish you off. You send your family away while you make your last stand AND... You die. As much as I did dislike the death, I do like the ending. It reminded my a lot of the ending of Gran Torino (Which ended in Eastwood's character tricking the local gang into opening fire on him in front of the police, so the end result is the same: His friends and family are safe at the cost of his life)
