Percentages

I'm talking about immunity to execution, just so you know. Maybe it would be more accurate to say not "lost," but "were killed." And is it really because of them, or is it specific to your game? In other words, if a player makes mistakes, executes peaceful creatures, kills peaceful creatures, makes wrong decisions about roles, ignores clues, and messes up the whole game, and then loses because of percentages, is that really their fault?
