I'll vote for a day extension but I'm not changing my vote for you yet. If you have a deadman bomb, you could still win this.
If we don't lynch today and you claim that you're going to kill A_Fey_Dwarf, the dopps can't kill you without wasting a nightkill since you'd be dead by morning anyway. If you lied about your target, this would mean that we would lose two town roles during the night.
At this point, the town would have only two remaining members and voting for you would cause us to instantly lose, assuming the dopps didn't join in with the vote. If we voted for A_Fey_Dwarf instead, we'd lose another townie and be left with 1 townie, 1 dopp and you. You could kill the remaining dopp at that point and the dopp's nightkill would decide whether it's a town or exterminator victory. The final option, voting for the other dopp, would leave two townies, a deadman bomb armed exterminator and a dopp warlock. Once again, the dopps would choose who wins.
If the dopps do decide to night kill you tonight, they would lose one person and we would be able to quite easily find the remaining one because there would be 4 townies against one dopp. While the dopps may attempt this, it does seem like a very big risk to take.
The final possibility is that we try to lynch a dopp today but then we're just guessing and that's exactly what you're telling us we can avoid. The only difference is that we have even less information than if we left it until tommorrow.
Overall, I don't see why you would decide to give up any chance of winning by killing the warlock so I'm going to vote for you unless you can convince me that you don't have a deadman bomb. At least this way, we stand a chance of you killing some dopps if you do have it.
