This is it!
One simple sentence: "There should be a little bit of penalty for killing everybody just for fun."
I have killed everybody in Lucula forest and Hunters edge. Just for fun. How big penalty you suggests for that?
Their ghosts will pop up from the dead bodies. The ghosts of the innocents will continue to roam, acting all innocent. The ghosts of shopkeepers will continue to shopkeep. They will sell you ghostswords and ghostbread and ghostscrolls. You can have ghostversations with them where they will talk about their ghostfeelings and send you on ghostquests.
Your true punishment is the knowledge that your actions, however violent, are ultimately meaningless.
You may kill them again if you wish. But what happens when you kill a ghost? Do they go to the after-after-life? Do ghosts have ghosts?
