If he was neither faction nor cult but according to you he was still anti town, that makes him SK?
a) He didn't have a personalized kill.
b) If he was on the team with FF then as I said, if FF was turned by Baal he'd go vig and rat out Wonk, ruining the balance and eliminating the possilibity of a kill other than the poison scum use.
It really doesn't make sense for Wonk to be anti town in this case, I think you're bullshitting.
Disconnect and self destruct, one bullet a time.
