One of the mafia is bound to be one of the inactives. Which one, I don't know. Hanako has done absolutely nothing to help the town. For all intents and purposes, she is anti-town and so lynching her isn't "a bad thing".

However we still don't gain much from it. But I'm more willing to off her than Souji for this reason: if Souji is scum, we will find more evidence to support it. Hanako has given us nothing, will give us nothing, and is probably trying to smurf us all over dawgs.
