If the scenarios, are:
Val has legit dees-This is pretty straightforward. Val is probably good.
Val is executioner-3 pups could be good, bad, or neutral. Val would be neutral and 3pups retains almost the same base chance of membership (minus 1 from whatever the n is for the neutral group, so slightly higher percentage than a random person of falling in good or bad vs. neutral).
Val has corrupt dees-Val good, 3 pups likely good.
The 3rd possibility is the much less likely thing. As, unless I've missed something in roles (admittedly I have not read all in depth), it would require the person making the corruption to guess right on one of two non-obvious targets on n1 (the night where there are the most potential targets for a night action). So, I can't rule it out completely, but certainly the first 2 are more probable.
