All of the stuff with his family, him fucking over his son in law, his son Charles, every time he gets into an argument his family just calls him a narcissist that only cares about his reputation and his stature, public perception, etc. They did a pretty good job of showcasing how his ego develops.
He is humble in the first couple of episodes but he still loves attention, makes his reputation in a show trial after all. But in the beginning, he's just trying to get noticed, to make more money for his family. After the Congresses, he feels he has to be the equal of all of these esteemed, well-landed gentlemen and so his ego starts to get the better of him.
And of course, the indignity of his Vice President tenure made him really bitter.
