I'll prove I'm a good guy even if I have to destroy this entire city and beat you to a pulp!

Uriah: Then I hope you have foreseen the consequences of a world bereft of religion.
The Emperor: I have. It is my dream. An Imperium of Man that exists without recourse to gods and the supernatural. A united galaxy with Terra at its heart. [...] These warriors shall be my generals and they will lead my great crusade to the furthest corners of the galaxy.

The Emperor: The difference is I know I am right.
The White Wizard: Sometimes you have to do difficult things if you want everything to be perfect. And I do want everything to be perfect. And I'm the living embodiment of goodness, so whatever I want must be good. D'you see?
Sam: OK! So, he's a complete nutcase.
