How exactly does the Dark Brotherhood passive Scales of Pitiless Justice work? Does it reduce an existing bounty for murders that have already taken place or does it only reduce new bounty for future murders after the passive has been purchased with skill points or maxed out? I have a character with a very high bounty in the millions from murdering, and I'm wondering if it would be worth the effort to level up my Dark Brotherhood skill line to get this passive so I ultimately have less to pay off or if the damage is already done.
