Yes and no. If there were more cycles left, then I would agree that killing someone who's defending you is generally a bad choice. But, as discussed before, this may be our last lynch cycle if there are two wolves. SOV supporting you makes his kill the one that would exonerate you the most and thus may be the perfect one to keep you from getting lynched for the last day you need. Alternatively, 1dog and someone else (DVMD, at this point, since I still trust WZ and buy your BSC reasoning) could have chosen SOV just so the two of us could take up day discussion with our argument and let them skate by.
From what I can tell, SOV yesterday ranked middle-to-low for wolf suspicions, tended to talk a lot, and had strong opinions. All of those traits make him a player who's death would cause chaos during this critical cycle. On a more personal note, I can't help but feel that his death is being used to frame me and buy wolves the last cycle they need.
This is part of why you've moved up my wolf-list today - you very quickly used SOV's death to try and shift suspicion onto me.
