Do you forget how the game works? The Communists win when their numbers equal that of the Citizens. Sacrificing half their numbers would just make the game harder for them. It's the fourth day, and the Communists aren't in any better a position than they started in. Worse, actually, if we account for the Indoctrinator acting on the first night.

So if that's my game, it's a pretty poorly thought-out one.
