1. Nettie only kills you, if you are really bad. She uses that as a last resort, when you don't work with her at all, because she and Halsin where just attacked by a tadpoled person and she is afraid, you might attack the grove. She is doing exactly, what most cautious people would do in her situation.
2. Freeing Halsin doesn't require killing goblin children at all. Those two never died in my playthrough - that is entirely your decision, if they die. Helping Minthara kills children though, without any chance otherwise.
3. Those goblins, that are not hostile, just attacked people in the wilderness, killed and roasted a dwarf and burnt down an inn, killing a lot of innocents.
So yeah, you were saying about siding with Minthara is not evil?
