The way I look at it, the SK is what's keeping the town alive right now. You think Zarni is the serial killer. You may be right, but you have no hard proof. However, the possibility remains that Bad Ash, Ankeli, or ThunderCat is/was the serial killer instead.
Let's assume for the moment the most likely scenario, that we have four townies, three mafia, and one SK. That's 4-3-1. If we mislynch, and Zarni comes up town, then it becomes 3-3-1. Mafia kills the SK (since it's between Ash and Ankeli now, and they know which of those two is mafia); it's now 3-3 and mafia win.
If Zarni is the SK, then mafia kills a townie tonight and it's now 3-3. Mafia win.
Different scenario: TC was the SK. We're instead 5-3 then. Zarni comes up town, mafia NKs a townie, it's 3-3 and mafia wins.
I'm going to bold this right now so it's perfectly clear to everyone.
Lynching Zarniwoop, no matter what his role, will allow mafia to win the game. The only way to stop this is for a successful doctor save. 25% chance of that happening, good luck.
Anyone who votes for Zarniwoop is scum.
Sathoris is scum. Yesterday Asrrin was the most scummy; today, it's Sathoris.
Asrrin is obviously scum, nothing has changed there.
Hell, if I wasn't sure KrazeyIvan was town, I'd call him scum too for his stunt yesterday.
