I suspect that there something more to the story of Sandalath and Phaed.
Superficially, Phaed is real bitch and she got what she deserved. We rarely get her POV though but only see her from the perspective of Nimander (and the perspective of Phaed within Nimander)
We see her first in HoC
Quote
One of the new Tiste Andii moved to the three noisily dying Edur and unceremoniously slit their throats. When finished, she raised her gaze to study Apsalar for a long moment.
Quote
'The search for loyalty and honour', Darist had said, with a sneer, whilst Phaed—the young woman who had shown mercy to Apsalar's victims—bound his wounds.
Quote
'No they ain't. See the tallest one there, with the long white hair. His name is Nimander Golit. And that pretty woman beside him, that's Phaed, his first daughter. All seven of 'em are cousins, sisters, brothers, but it's Nimander who leads, since he's the oldest. Nimander says he is the first son of the Son.'
Then in BH, we see that Phaed is the daughter of Envy and Nimander
Quote
'Ah, you're not completely blind, then. You can see, can't you? Different mothers, for some of 'em. And one of those mothers wasn't no Tiste Andii, was she? Look at Phaed—' 'I can only see the back of her head.' 'Whatever. I looked at her, and I asked her that very same question you just asked me.' 'What?' '"Who was your mother?"' 'Mine?' 'And she smiled – and I nearly died, Banaschar, and I mean it. Nearly died. Bursting blood vessels in my brain, toppling over nearly died. Anyway, she told me, and it wasn't no Tiste Andii kind of name, and from the looks of her I'd say the other half was human, but then again, can you really tell with these things? Not really.' 'No, really, what was the name?' 'Lady Envy, who used to know Anomander Rake himself, and got her revenge taking his son as a lover. Messy, eh? But if she was anything like that Phaed there, with that smile
Well that makes Phaed (and Nimander) part Azathanai. Phaed being even-more Azathanai than Nimander. (because of Incest, yuck)
Later, Phaed as part of Nimander has quite an important role in TTH and CG.
Nimander himself seems to be quite indecisive in many situations and Phaed actually helps him in several situations.
Now, coming to Sandalath, she herself is quite broken and is actually given life by the Crippled God in MT.

Something with a voice. These are restless seas indeed. I had not thought my questing would prove so . . . easy. True, you are not human, but you will do. You will do.
and then in CG, Sandalath almost destroys Kharkanas until Phaed takes her out of the picture.
Is it possible that Sandalath was an agent of the CG and Phaed actually tried to kill her early to prevent Sandalath from causing all the trouble.
