Batman: Arkham city

Aaaaa... kill each other. In short, let me explain how I see it. Arandor and Kosha are both negative. Since they are not linked, it is likely that one of them is Mafia and the other is Town. You could, for example, build the following branches: Kosha-Arandor and see what happens. But everyone chose (I still don't know why) the branches Arandor-Amko. And if we compare who is more negative of these two, I would prefer to execute Arandor now. That's it.
