I don't concur. I think it should be possible. To have the option to work out something with him like you could with Ifan, the demon, or Dallis and... the other guy.
It is also annoying to have no reason to think that Braccus is the only one that you should focus on. It is the Kraken which summons everyone else, and as far as I could tell, Braccus wasn't soul-bound to the Kraken, so there was no reason to believe they were linked. And given that it is the Kraken which summons un-ending bad guys and has huge AOE attacks, it seems reasonable to assume that you need to focus on it, not Braccus.
Also, the game cheeses and sticks your party as far away from him as possible if you accept getting purged. I had to object to it, move everyone to crowd around near Lucian, and then attack Braccus until he went hostile just to end up with my party in a "fair" position. It literally tries to default to put you in the worst position possible for you at the beginning of combat.
Very much despise that final combat.
