I thought I had it down to three distributions of evil without any questions, but I made a minor wrong assumption about one character being either innocent or corrupt without realizing they can also be evil, which opened up quite a few more valid solutions still...
I think its possible to win this one 100% of the time. The unlocking piece of logic is figuring out where Chancellor/Minion must be. (And of course the rules for how demons disguise!)
This is also a really good example of a game where it is helpful to kill a useful villager to know their alignment so you can use their powers with certainty and judge the other villagers who are making claims about the person you killed. You don’t have to to win, but it can help!
Yeah I had to get some sleep but next day I listed all variants, but I can't be arsed to design the right "algorithm" of using the abilities now. Possibly you can have 100% solution, yeah, it's just that I tend to naturally enjoy the passive informations analysis more than deciding how to use abilities. Save them for the end typically and usually if there are abilities to use, they are abundant and you don't have to think hard on how to use them cause you have more than you need.
