I said "personal glory", not "revenge". Of course Siuan has a motive to help Egwene, but she could easily have supported Lelaine or Romanda with similar results (her support would have tipped that balance, I am sure).

And as Egwene said, the Stilling and Deposing of Siuan was invalid since there were BA in the Hall, so technically Siuan is still Amyrlin.

Most of all though, Siuan has been a constant friend and mentor. It is made clear by RJ/Brandon in Rand's chapters that when he gets angry at friends who disobey orders or criticise him for the right reasons (for example, Nynaeve telling him not to strike at the Borderlanders), he is wrong to be angry (and in fact, we see that he even knows and understands that Nynaeve is correct).

Contrast this with Egwene, who knows that the Seanchan could still be around (she never even asks about or considers the huge danger posed by the BloodKnives, one of whom could easily have killed her) while she was unconcious after the battle. Her own logic of her self-importance dictates that her life is invaluable at this point, so why she got angry at Siuan for preserving it is completely irrational. Why is Egwene any better than Rand in this case? I think that in fact, she is WORSE, because she fails to think about WHY the order was disobeyed, and she can't understand or forgive a friend (who has not once failed her) for it.

And as I said, Siuan accepting the judgement means nothing. A major theme in Egwene's plot line is that just because nobody protests an action, does not make that action right.
