He's not a coward for not killing his main character. Still a business, the story can't go without the main character.
Even though historically, the real man Shin was based on died right here.
It's that he's using this stupid-ass life-sharing deal. The ENTIRE POINT of Houken was to find a way to cause the physical to become supernatural. And yet somehow Kyoukai has supernatural magical arts already. Had them for a thousand years!
