"But I feel like griffon-sama only said something really obvious though" Of course, that drugged looking animal just say what any other one would, 'If I really shouldn't do it then I wouldn't be able to'. The author when from a righteous mythical beast at the beginning to a beast promoting corruption of power.
I don't really mind it, but when an author wants to do a higher moral character and fails miserably like this, it kind of piss me off.
