Quote #4
BLACK WIDOW: So, Banner... that's your play.
LOKI: ...what?
BLACK WIDOW: Loki means to unleash the Hulk. Keep Banner in the lab, I'm on my way. Send Thor as well. [to Loki.] Thank you... for your cooperation.
We really, really like this moment a lot: when Loki the player gets played by a woman he referred to as a "mewling quim." In its own way, the Black Widow's rebuke is a sharper form of justice than simply locking him up. She beat the bad guy at his own game.
Quote #5
TONY STARK: There's no throne, there is no version of this where you come out on top. Maybe your army comes and maybe it's too much for us but it's all on you. Because if we can't protect the Earth, you can be damned well sure we'll avenge it!
Part of administering justice is knowing where responsibility for the crime lies. Iron Man took a while to get with the program, but it's pretty clear who he—and the rest of the Avengers—are pointing their fingers at for this one.
Quote #6
CAPTAIN AMERICA: You think you can hold them off?
HAWKEYE: Captain, it would be my genuine pleasure.
Hawkeye has reasons to stick it to Loki, but he sets it aside for the bigger picture. That's the difference between justice and revenge: justice is about fairness and protecting people, while revenge is all about personal satisfaction. Freed from Loki's mind-blender, Hawkeye has no doubts about where he stands.
