Fine, whatever you prefer. I'm saying this guy writes interesting stuff.
He also says that the nonlethal options for dealing with targets, while each more horrifying than the last, fits quite well in honour culture when you consider they're all Corvo's revenge in action. Each causes the target to be stripped of their social status and cast out of the elite, either by the actions of their peers or the actions of others. Since this is exactly what happened to Corvo, the nonlethal options are a more appropriate form of revenge, contemporary morals aside.
