It would also make more sense for Minthara's story if she was
being punished at Moonrise for losing her army, rather than successfully wiping out the TIeflings and Grove, which is how it is at the moment.
I would say it actually makes more logical sense that you
can't recruit her if you sacrifice the Tieflings and Grove, as she would be rewarded and indoctrinated further into the Absolute's cult.
The only way it makes sense to save her from the dungeons and recruit her is
if you successfully wipe out the goblin army leaving her (and maybe the other leaders) alive to be punished by Thorm.
But there's a lot of narrative flaws like this in the game.
