Man, all the father figures in this manga are actually shit individuals, from Gambino who sold Guts for a night to the King who lusts after his own daughter. I will say that Griffith can read people so well. Just from his intimate night and being "tortured" he was able to call out the King...
"His dream is so grand and pure." Really? What exactly do you know of his dream other than it being a push for power. Looks to me like he will use anyone as a tool for himself, no matter the consequences they will have.
