Hi. I've got an outlandish speculation about Rheagar's actions(it is as outlandish as mermen Varys:)) i think there is possibility that he knew his destiny via Bloodraven or Ghost of Higheart. they showed the future and told him that the only way for victory against Others is for him to die in trident and for Jon Snow to live this way.( i know his conversation with Jaime puts big hole in this this so called theory:)). So does his sacrifice make him a hero?anyway it could be a fanfic:))
many think that that Rhaegar acted to fulfill a prophecy, although it is not entirely clear what prophecy. From what I recall (don’t have the books with me) Rhaegar thought that his son Aegon (the one that was killed by the Mountain) was the Prince that was promised since he was born under a ‘bleeding star’.
Bartistan (I think) tells us that Rhaegar first thought he himself was destined to become the Prince and stopped making his music and poetry and instead became a fighter. Daenerys sees him in the HotU as he tells Elia that their son Aegon has a connection to Ice and Fire ('his is the song of Ice and Fire’). He also says that the dragon needs three heads, another possible prophecy.
It has been argued that Rhaegar needed a third child and therefore abducted Lyanna to get this child, maybe because sometime between the birth of Aegon and the tourney of Harrenhal he decided a Targ-Stark was needed, or because he wanted a Visenya for his Aegon.
So, we only get hints at what prophecy motivated Rhaegar and we don’t have any specifics. Considering that we have multiple hints in the books that prophecy is just not safe to follow or to even let it influence one’s actions, there would always be the problem that Rhaegar might have been wrong simply because he tried to ensure that a prophecy is fulfilled. We see many problems with prophecy in the books. There is Cersei who does everything to prevent her prophecy of the younger Queen from happening and by doing this she tightens the ropes that will be her downfall. Then there is Daenerys who seems to have accepted that the prophesied treason will happen, but still thinks and thinks about them and tries to identify them. It is my opinion that she’ll misidentify them and will feel secure and then the prophecy will bite her on the ass. The three treasons will happen when she thinks treason is behind her. Then there is Stannis, for whom Mellisandre tries to bend prophecy. She ensures that he got the sword ‘lightbringer’ which we already know to be false, and by this Stannis will finally be convinced that he fulfills the prophecy. I think that he’ll try to ensure his victory and his destiny by sacrificing Shireen and this will be his downfall.
So, we have three kinds of dealing with prophecy: trying to prevent them (fail), trying to identify them (fail), trying to make them bend to point towards someone (fail) and then we have Rhaegar who tries to ensure that a prophecy will be fulfilled (which is a little bit different than trying to bend prophecy I’d say).
Now, it might be that Rhaegar’s method is the only way how to deal with prophecy, but I must say that I doubt that. I argue that like GRRM has one of his character’s say: Prophecy is like a sword without a hilt. There is no safe way to handle it. In addition we have one example of someone who fulfilled a prophecy: Azor Ahai of legend who forged Lightbringer by tempering the blade in his beloved wife’s blood. We hear about this story through Davos’ PoV, a decent enough guy who is shaken by this story and thinks that he is not the stuff of heroes and could never do a deed like that. Davos is also the person who tells us the following:
"I know the cost! Last night, gazing into that hearth, I saw things in the flames as well. I saw a king, a crown of fire on his brows, burning . . . burning, Davos. His own crown consumed his flesh and turned him into ash. Do you think I need Melisandre to tell me what that means? Or you?" The king moved, so his shadow fell upon King's Landing. "If Joffrey should die . . . what is the life of one bastard boy against a kingdom?" "Everything," said Davos, softly. (ASOS, DAvos V)
And I think Davos is right. No one should do that. No one should sacrifice a human life for a prophesied outcome that might not come to pass, because the interpretation of prophecy is such a tricky thing. In the books Stannis will die realising that he sacrificed his girl for nothing. Why do we see that human sacrifice is the wrong way only for it to be rigth in one case? No. I don’t think so.
So, how does that tie in with Rhaegar? So, even assuming Rhaegar was right in his interpretation of the prophecy, it should still not have led him to do things that are questionable at best, things that endangered the peace in the seven kingdoms and by extension the very results he wanted. He, however he did it, abducted the teenage daughter of one of the most important lords of the realm. His behaviour led to a civil war that cost thousands of lives, including the life of the father and the brother of the woman he supposedly loved. He endangered the lives of his first wife and his other children, leaving them to the mercy of a madman or alternatively to the mercy of his bitter enemies. He left his second wife in a tower under guard, where it was impossible for her to prevent that her guards and her only remaining brother fought to the death. So, even if we ignore the evidence of Jaime’s memory that Rhagar intended to win, and allow for him to be prepared to die to ensure Jon’s survival, all these actions are not the actions of a good man. You do make an interesting point that he might have been driven to do that by Bloodraven - who might me much more sinister than your average old wizard tutor.
Does this make Rhaegar a hero? Maybe. Azor Ahai was called a hero after all. That does not make him a likeable person.
Even if Rhaegar was absolutely convinced that he had to ensure the prophecy he was after even at the cost of his own life, he is still to be held accountable for his sins, and there are many of them. Being prepared to sacrifice one’s own life for a ‘good cause’ does not ensure that the cause is good nor does it wash away other deeds. It is more complicated than ‘self-sacrifice makes a good man/woman’. Though you might admire the courage it takes to sacrifice one’s own life, it says nothing about his or her cause, it only says something about the conviction of the person in question.
So admiring this person’s conviction might bring you to think about their cause, but I’m with sceptical Davos here. What is the life of one bastard worth? Everything.
I strongly suspect that in ASOIAF there is only one way how to deal with prophecy: Ignore it. Because as far as I can see every other way leads to disaster. I strongly suspect that Jon at some point will be told about the prophecy of Azor Ahai and will choose to ignore it.
I’m a bit sorry for my strong reaction to your ask, but I am very wary about heroes, because a courageous act can be done for the wrong reasons and for a wrong cause and what remains of heroism then? I’m also very suspicious about Rhaegar if only because we know so little about his motivations.
That should not prevent you to write anything you like in fanfic... In fanfic we can have inescabable love potions as well as inescapable prophecies, and I must admit that it would add to the somewhat tragic arc of Rhaegar if he at least knew that there was a chance he would die.
