But you haven't yet gone back to PPS. All you've said is, "I want to see how the vig plays out." I think that's bad, because scum almost certainly are able to regenerate, or roleblock, or something else that would mess up the kill. Hell, PPS was the first one to bring forth regeneration, right? That means that if PPS is scum, he or a teammate have regeneration or a way to cause regeneration.
But you haven't even considered lynching PPS anyway. I know if I believed that PPS was scum, I'd probably be voting there regardless... but you haven't appeared to be putting any thought towards the issue. It's something worth discussing, at the very least
Town has a lot of incentive to talk about PPS if he turns out to be scum, because the answer to "Should we lynch him anyway" isn't immediately obvious.
Mafia has an incentive to back off, because they don't want to waste a mislynch on someone who is possibly getting killed tonight anyway.
I don't think town who thinks PPS is scum should say, "Nah, let's wait til tomorrow". Scum wants to do that more, IMO.
