Henry Jekyll
While alive, Moriarty awakened Mr. Hyde, who is called evil, by setting a trap. He does not even consider that fragment evil. Since he considers it as something like, “Because, for him to exist individually, that itself is his achievement.” Because it looks like he will be killed if he puts that into words, he has been refraining from doing so.
Although Moriarty utters, “I want to get along with him”, this is relatively what he really thinks. Because after all is said and done, the works he sent out at a whim will be playing an active role for the sake of the world.
