I understand we're talking fictional stuff here. But even in the fictional book that Rand and Tex and countless other brainwashed folks worship, the One was sacrificed for the sake of humanity. Half of the universe's population now dead while Ironman lives? Unjust. Ironman has saved a bunch of lives, but there are plenty of other superheroes out there to take his place. Strange should have let Ironman die, and then avenge his death with the other Avengers.
