He is what he is. An arrogant, narcissistic a-hole who cannot stand to be around those who he believes are lower than he is. And that is everyone.

Oh I think he is far more disdainful than we believe. If he spoke what he truely believed we wouln’t be in this Hellish nightmare! He has fooled the weak minded but even they would be horrified with the truth.
