Oh yes, definitely.
That one's easy enough. They've been killing "confirmeds". Psychotic, Cid, foa. If they'd killed someone we were less sure of, for example, theundeadhero, then that removes a suspect and makes us less likely to find someone. Here's a thought: Leeza is also a confirmed. Why not kill Leeza?But I don't get why they killed foa since foa was suspious of theundeadhero and eestlinc.
