A dead Mafia member when playing with clues is a disadvantage for the Mafia because, when analyzing the clues, they can shift the blame to the murder of the Mafia member and focus attention on that murder.
Without a Serial Killer, the Mafia has no one to kill at night.
Our fierce paladin risks making a mistake and killing a super-useful Thief instead of a Mafia member, and in general, she might get a good character during her check, and then the night is wasted.
