Well all countries need a government under the sign of modesty, well-balanced, with morals, respect and always thinking of others, but seeing as that tends not to be achievable most of the time, I'm not sure what that has to do with anything - especially if what LadyFinn has posted above is correct and that the decision was taken together and seems to have come more from Nicholas than anyone else.
If Nicholas has come to the decision that he cannot fulfill the role then IMO it was better to share this with his grandfather and aunt now rather than later.
