It would be very difficult to run a classic "DDmafia scenario simulation (TM)" because of the large number of factions and the chance of killing roles choosing the same target to kill, etc. Difficult but not impossible. I won't do it now but might later.
That would be interesting.
Consider this though... There is a 40% chance that you are on a Serial Killers kill list. If they decide who to kill off of their list randomly that is a 20% chance of you not waking up tomorrow due to an SK killing you. If you help secure a lynch lynch then there is a chance that we hit an SK and if we hit an SK then the chances of you being on an SK kill list drops to 20%.
There is a 1/6 chance of hitting an SK with a DP1 lynch. It is much more likely that we hit an SK target, someone who isn't an SK target (thus reducing the size of anti-SK coalition while doing nothing to stop SK from fulfilling their wincon), or worst of all, someone who benefits us (power roles). The potential risks that can come with a random lynch DP1 outweigh the benefits, as explained by the original argument.
There is also the chance that mafia might decide that you advocating a pro-SK VTNL makes it likely that you are an SK so they might shank you.
Possibly. But at this point, we have no idea who mafia are, let alone what they are thinking. Similarly, they are just as in-the-dark as we are about this entire situation, so they probably wouldn't jump to conclusions that quickly. Also, arguing for a DP1 VTNL is not inherently pro-SK, as demonstrated by the reasons I provided.
Right now it's 11:30pm, and I'm pretty tired, so I'll provide the rest of the argument tomorrow. GN.
