We've had this discussion before I thoroughly enjoyed it. But I think Mystra should have / would have returned Gale-Bomb Gale to life just as the Green Knight declined to take Gawain's neck.
At this moment Gale redeems himself, he self actualizes, he conquers his shadow. He has defeated his fundamental flaw - his Hubris. He acknowledges that his hubris brought him to this place - not the evil doings of his crazy ex. And he is prepared to make amends, he put the world in danger and his sacrifice can fix it. He can save Faerun and all of magic with a snap of his fingers. And does just that. All hail Gale, hero of Baldur's Gate
