Rutger Hauers quote at the end of movie Bladerunner
I've... seen things you people wouldn't believe... Attack ships on fire off the shoulder of Orion. I watched c-beams glitter in the dark near the Tannhäuser Gate. All those... moments... will be lost in time, like tears... in... rain. Time... to die...
And of curse the Edmont Burke:
The only thing necessary for the triumph of evil is for good men to do nothing.
