What does Twain admire in a man and what is he contemptuous of?

This is more an opinion question rather than stated fact. I would speculate that Twain admires a man that has his own social code and is not afraid to act against the unjust social norms of society. Twain would not like men, like the King and Duke, who cheated and betrayed others under the guise of being harmless clowns.
