This is a good chapter. This actually show the harsh realities that occurred in the Middle Ages. We can't ignore that, and it's amazing that this manga puts into light such drama!
By remembering the harshest parts of history, we, in the present, are able to evolve into a better civilization.
If we continue to censor this, then we'd probably have more serial killers who don't realize the gravity of their act to other people because this actually helps with them becoming a more empathetic individual.
