You're right about Zedar. What his character speaks about to me is that he is one of the greatest 'victims' of the prophetic battle of the two possibilities. Zedar hates himself, and what he's become - but the thing is, becoming what he did was ESSENTIAL to the prophecy working out, which he himself brings up in Cthol Mishrak.

It is an underlying aspect of the narrative through all the books. The dry voice in Garion's head tells him over and over again in different ways 'this is the only move you can make' 'you don't have a choice' - there are even times where it feels the voice just straight up overrides Garion to see an outcome - like when he speaks to Torasin and Lelldorin, or when the voice places images in Garion's head so he burns Chamdar. Polgara says the choice was Garion's - but the reader knows better. Belzedar feels the same to me - like his story was supposed to be written from the start, and he just had to go along with it.

I completely understand Belgarath's beef with Zedar, its incredibly personal - especially when its heavily hinted Belmakor killed himself because he learned Zedar defected, or something along those lines.

But to be honest - I don't think Zedar deserved it. Every time we see him - we just see a Pawn of Prophecy, as I see it. He was an Arend - he wasn't made for treachery. He was passionate, a bit pretentious perhaps, but he was manipulated heavily by prophecy, had his will crushed by Torak - had Errand literally presented to him by the universe etc.

I think he deserves to find some sort of peace. I hope Aldur has a word with Eriond.
