I got another idea (somewhere below there are two ideas). You can make the dead see who the impostor is, so it will be interesting for them to watch the development of the game. (I use a translator, so there may be inaccuracies)
That’s actually a nice idea and I’ve heard it before, however, this might ruin the fun. Not knowing who the impostor is basically what the game is all about. Anyway, the ghosts the impostor killed will know whom is the impostor already.
