Quote #4
NICK FURY: You think you could make Loki tell us where the Tesseract is?
THOR: I do not know. Loki's mind is far afield. It's not just power he craves, it's vengeance, upon me. There's no pain would prise his need from him.
NICK FURY: A lot of guys think that. Until the pain starts.
THOR: What are you asking me to do?
NICK FURY: I'm asking, what are you prepared to do?
THOR: Loki is a prisoner.
NICK FURY: Then why do I feel like he's the only person on this boat that wants to be here?
Nick Fury stands at the balance between good and evil in this film. He's definitely an ends-justify-the-means kind of guy. What does that say about who he is?

LOKI: It's an impressive cage. Not built, I think, for me.
NICK FURY: Built for something a lot stronger than you.
LOKI: Oh, I've heard. The mindless beast, makes play he's still a man. How desperate are you, that you call on such lost creatures to defend you?
NICK FURY: How desperate am I? You threaten my world with war. You steal a force you can't hope to control. You talk about peace and you kill 'cause it's fun. You have made me very desperate. You might not be glad that you did.
This is a classic hero vs. villain showdown, though Loki has a point: the Avengers aren't exactly knights in shining armor at this point. Part of their journey is finding out just what a force for good they can be.

CAPTAIN AMERICA: Phase 2 is SHIELD uses the Cube to make weapons! Sorry, the computer was moving a little slow for me.
NICK FURY: Rogers, we gathered everything related to the Tesseract, this does not mean that we...
TONY STARK: I'm sorry Nick, what were you lying?
CAPTAIN AMERICA: I was wrong, Director. The world hasn't changed a bit.
Stark and Rogers may butt heads from time to time, but they clearly both have well-defined senses of right and wrong, and neither of them are willing to let Fury off the hook because of it.
