she is drow and evil so by the laws of the area that is enought to kill her on sight
she also uses sex to get her way and [between bg1 and 2] we learn she was raped and killed them for it
for the record i also play No-Reload with SCS/Ascension and have gotten 1 character to the end... several dozen didn't of course but i agree she works better [story wise] as Neutral
this is a good example of evil characters being worth your time to learn, her story is complex and you can easy skip all of it by saying to that first Ironfist merc "yes she is evil so go ahead and kill the bitch"
