One thing I always think of when people celebrate an awful person's death is A Christmas Story. Specifically a scene towards the end when the Ghost of Christmas Future is showing Scrooge what his lifetime of cruelty and greed will beget him. Simply put, there's a scene where Scrooge and the ghost watch as his former servant and her friends gloat over Scrooge's death, as she sells them his bed-sheets and drapes. Bed-sheets and drapes she shamelessly took from his room while his body was still cooling and stiffening within it.
And, like, the thing is — the message the narrative (and Charles Dickens) is trying to put across here isn't that these people are wrong to be celebrating Scrooge's death or even to be profiting off of it. In fact, the message that the ghost is specifically trying to impart is that it's Scrooge who is the problem. It's Scrooge with the moral deficiency. It's Scrooge who has to change if he wants people to be anything but delighted and opportunistic after he dies.
Something something you reap what you sow. Something something if all you ever do is treat your fellow man callously and cruelly and nastily, do not be surprised when people smile to hear that you've died — and steal your fucking bed-sheets.
