If you hold off, you can find more evidence in the swamp near where the hag has her place and then you can convince Kagha to turn away from the Shadow Druids and join your side and she is horrified at what she was doing.
I kinda would like to have the option of having either her or Halsin as recruitable druid. Maybe have the option of her coming with you as a redemption/atonement situation if you manage that.
To be honest... I'd love to have two to three characters of every class capable of being recruited so you could get various flavors of party based on what you want to play. I mean, I love Shadowheart, but I gather there are some that would appreciate being able to have a different cleric available for recruitment.
