So? Your idea of morality is "they are stronger than me, so anything goes"?

And explain to me what advantage Alanna's warder had over a group of Whitecloaks. Yet they assassinated him, rather than facing him up front. Given your belief that they would have been justified in killing Perrin since he attacked some of their group, Alanna too would have been justified in just destroying them in the blink of an eye. Yet she doesn't. Which makes it pretty clear which group has more checks on their powers.

And it isn't as if their war is by any means rational or justified. Aes Sedai are by no means a bunch of Darkfriends, and have contributed a lot more to checking the power of the Shadow. One would think, given how often you bandy "PoV trap" about, you would pay some attention to it here. Just because the Whitecloaks think it is true doesn't make it so, and doesn't make it true.

Added to this, the fact that Aes Sedai cannot open hostilities against Whitecloaks (and have never shown any inclination to anyway), makes it clear that the advantage is all with the Whitecloaks. Aes Sedai cannot (and will not) even systematically kill any Whitecloak they see against a future chance of assassination, a course which the Whitecloaks themselves seem to
consider morally valid, as do you.
