To flip the question on it’s head, why didn’t you save Bridenbrand? At this point in the game, you are one of the most powerful champions in the world. You’ve defeated Onyxia, Nefarian, an old god in C’Thun, and even Illidan, who the Naaru were fighting against. And yet, despite your power, you cannot save Bridenbrand because you are not that powerful, or you were not there when your aid could have been of use. Your power, vast as it is, has limits.

The Naaru are similar beings, and have never been presented as more than that. Their power may be more than yours, but it is still bounded.

Thus, it is unfair to complain about what they could have or have not done. If you had been present at the battle where Bridenbrand was infected, maybe you could have prevented it. Your character is certainly powerful enough. But there is a difference between an omnipotent being and a being who’s power is bounded. And it is unfair to complain that a limited being does not act like an omnipotent one.

As an aside, I’m Jewish (albeit not v religious these days) so I wasn’t brought up in a religion that either believes that everyone is damned and needs to be saved, or that only people of the same faith as me get a pass into heaven (as far as it goes, we believe people will be judged on their deeds not their beliefs). I think this is where the disconnect comes.

But it is still interesting to toy with some of these ideas in a game.
