I think Larian should deepen the antipathy one feels towards the substitute druidess. I mean, before I met Halsin, the druids in the grove were really selfish (except 1) and disdainful of refugees. And since we can (depending on the path we take) meet the pretty drow before to meet the imprisoned druid, it would be pretty smart if she tries to manipulate us by saying that the grove ritual will eradicate the area, killing the refugees and locals. Moreover it would make this choice look like the "right one" because we choose either to save the people, or to heal ourselves with the druids of the grove. Especially until now the people who propose to treat us have all failed...
It would be a good idea to create a funny friendly goblin with whom we create a link, making us feel guilty for razing his village to the ground. The one we saved just makes me want to set fire to the first goblin camp I come across because it smells of betrayal from far, far away.
Sorry for my english, say it if you dont understand my though.
think empathy towards the substitute is based on your character. One playthrough I saw her point, do to her desperation, and one of the things in her cut scene. Another I didn't let the cutscene play out and just killed her. Another I tried to intimidate her, another persuade her. I've killed her, knocked her unconscious, all depending on my character. I've missed lore because my character couldn't be bothered with it, so pretty much empathy towards her is based on what you think your character would do. Also if you notice some things in her cutscene and can try to read her feelings through what can be interpreted or misinterpreted by them. Then theirs dice rolls, etc. So lots of options to take, just which is best for what your character wants to do. Of course new things down the road may sway them, or make them regret a previous decision.
