We're Alive REP-ivia!!!

[Witch_Doctor]

Question:

This is a two parter. A quote of a quote. What character says the following quote from a movie?

SPOILER 

"We will spare your lives. Just walk away."

Name the character and the movie.

Gonna have to give this to Wicked Sid. He answered the name of the We're Alive Character and the movie from which the quote originally came.

SPOILER 

Burt quotes the character Humongous (I have no idea if I've spelled it correctly) from the film Mad Max 2 (The road warrior?).

Man, writing clear and fair questions is harder than answering them.
