What themes could be surrounding Hippolite?

[staka]

I see and hear about many themes surrounding the main character Prince Myshkin, but rarely any with Hippolite. He is dying and starts to notice the significance of the world and the environment around him. So what exactly, are the themes surrounding the character Hippolite?

Hippolite is obnoxious: self-centred, greedy, offensive, fawning and miserable. Yet the prince loves him in spite of that.
