1 its possible to have Minthara without killing the druids and horn kids
2 the druids are happy to kill those horn kids and in fact saving a kid from the druids is one of your first quest options on reaching the grove
3 its possible to have both Karlach and Minthara or Karlach and Wyll ... its even possible to have all 3 but i assume thats a bug
4 Minthara is evil, there is no getting around that but its the bug in her head that wants the druid grove wiped out
5 it was possible in patch 1 to have both Minthara and the carebear but Larian changed that in patch 2 along with other untested changes and hotfix 8 now undoes one of those but its 85% sure they should not be together
now with that out of the way there is evil and there is Minthara, one quest is killing the grove or saving it and the other is having Minthara or killing her... be clear about which you are thinking about
