"Dog carcass in alley this morning, tire tread on burst stomach. This city is afraid of me. I have seen its true face. The streets are extended gutters and the gutters are full of blood and when the drains finally scab over, all the vermin will drown. The accumulated filth of all their sex and murder will foam up about their waists and all the whores and politicians will look up and shout "Save us!"... and I'll whisper "no."
-Rorschach, Watchmen
Brings a chill down my spine every time I hear it
EDIT: because Rorschach kicks so many balls
"You see, Doctor, God didn't kill that little girl. Fate didn't butcher her and destiny didn't feed her to those dogs. If God saw what any of us did that night he didn't seem to mind. From then on I knew... God doesn't make the world this way. We do. "
"None of you seem to understand. I'm not locked in here with you. You're locked in here with *ME*! "
"I shall go and tell the indestructible man that someone plans to murder him."
Rorschach is the most hardcore, craziest, best superhero ever. That man is terrifying, and just about every pre-asskicking thing he says is really scary.
But, for sheer horror and awe, I have to go with the things Sovereign says to you in Mass Effect:
"
You exist because we allow it, and you will end because we demand it."
It is just so scary, the creeping realization that you are a pathetic, miniscule creature compared to this all-consuming, omnipotent, immortal god-machine. Of course, it makes it all the more awesome when Seth Green kills the holy hell out of it.
Edit: I've been ninja'd. Thus, I will take this opportunity to throw in a different quote.
"
Your words are as empty as your future. I am the vanguard of your destruction. This exchange is over."
*shivers*
Whew. Can't wait to see how it ends. Too bad I'll have to... FOR A WHOLE YEAR!!!
