There are a number of factors that enter into Abrogail's decision here.  One of those is that, in her cold judgment, if Sevar goes with Keltham to Osirion, their cleric of Irori is not coming back.

Another is that it is not, even now, overdetermined exactly what manner of story this may be; and it may not be too late to establish that Keltham must become more Evil than this to win Sevar's heart and her ownership.

Had Sevar sold her soul, the decision would be more fraught; but Abrogail thinks she would make it this same way.
