I doubt I was the only one who took umbrage to her message blaming others for the death of Futayo. [ though other people would probably take umbrage for different reasons ] For some people, disliking a person is reason enough, unless humans and Galra are less alike than I thought. Though there could be other factors. She could have been viewed as a threat, or gained dangerous knowledge, or it could simply be that the killer understood she was disliked and thus the group as a whole would not be especially motivated to find her killer.
