I will speak of the dead how they were, not how I wish they were, and especially not how the dead wish they were spoke of if it has no basis in how they conducted themselves in life.
It devalues people that lived empathetic, caring lives, it devalues the lives of people who struggled their entire life but never used that as an excuse to exploit or otherwise harm others to play pretend some greedy/malicious/antisocial garbage human was a "great guy."
Don't speak ill of the dead? It's nonsensical. There is no God, but judgment still should come for a person, by the people whose lives they touched for better or worse, and it helps no one to pretend everyone who died was awesome.
Maybe if the world called a notorious POS a notorious POS when they died and tossed their corpse into a dumpster, it would, I don't know, show the living that how they live will decide how and if they're remembered.
