Old Text versus New: Genchu now talks of having a goal here but the old text made it clear that he was considering the good of the Clan.
I’m going to rely on context to make the connection that Genchu cares about Yorikiro and therefore the future of the clan.
If it were a matter of revenge, Hirotomo would be dead. If it were a matter of Yorikiro’s safety, that could be achieved by taking him into hiding. Instead, Genchu is giving him a position of power over a major clan – not an easy job.
So in other words you are relying on people not being idiots?
I love how harsh the colors are on this page.
