the narrative of the Kazuya path may vindicate (their version of) Tokugawa, but the other paths have different narratives, and it's not clear that the Demon's Bond writers would ever seriously argue in favour of Tokugawa's actions outside of fiction.

I absolutely agree and it's one of the reasons I think they handled it in a very clever and nuanced way.

But if it's not offensive, then it's not 3, because I defined 3 as being offensive ;)

That is very logical. ::nods::
