Win-Win is actually beneficial for the town. Because during the day, the Mafia is executed, and at night, the Serial Killer draws the attention of the Hypocrite's ultimate ability and the Mafia's kill, so the town survives the night without losses.
I find Revan and Gumer suspicious, as I already said. The first one simply comes, leaves a couple of posts, and leaves. The second one "investigates," but doesn't provide any evidence, and doesn't get modkilled for the investigation.
The answer is not only detailed in my post, but you can also see it right above your post.
Anyway, I've given my assessment of the Mafia roles and the meaning of executing specific players. According to my intuition, Lynx has a chance of being a town member, but it's a very small chance. And if she's so confidently accusing me of being Mafia, then we need to understand that it might not be about emotions, but about the fact that the Mafia probably has its own reasons. Not in terms of motivation, which is already clear, but in terms of the distribution of roles among the players. There are ways to deal with a killed Monster, including bypassing the Hypocrite's schemes, and there are even ways to do this by following the Night phase order. You know them, but I won't recommend or not recommend them, because the Mafia will take advantage of it.
