How we cite our quotes: All quotations are from Deadpool.
Quote #1
COLOSSUS: I've given Deadpool every chance to join us, but he'd rather act like a child. A heavily armed child. When will he grow up and see benefits of becoming X-Man?
NEGASONIC TEENAGE WARHEAD: Which benefits? The matching unitards? The house that blows up every few years?
COLOSSUS: Please. House blowing up every few years builds character.
Colossus and Negasonic Teenage Warhead show that even superheroes have shades to their character, and their attitudes about heroism. He's disciplined and staid; she's sarcastic and jaded.
Quote #2
RECRUITER: The world needs extraordinary soldiers. We won't just make you better. We will make you better than better: A superhero.
WADE: Look, Agent Smith, I tried the hero business, and it left a mark, but if I ever hit "f*** it," I'll look you up.
Throughout the entire film, Wade's reluctant to join the X-Men and be a straight arrow superhero. This exchange is the closest we get to a reason why. He never goes into detail about what this metaphorical mark is, but it sounds like his military career left him with some emotional scars.
Quote #3
DEADPOOL: Let's pro-con this superhero thing. Pro: They pull down a gaggle of ass. Local dry-cleaning discounts. Lucrative film deals, both origin stories and larger ensemble team movies. Con: They're all lame-ass teacher's pets.
COLOSSUS: You know I can hear you.
DEADPOOL: I wasn't talking to you. I was talking to them.
Deadpool and Colossus are at opposite ends of the spectrum in their views about heroism and goodness. Colossus is by-the-books, and Deadpool knows it. That's why he enjoys teasing him so much. While Colossus is all-in re: superhero stuff, Deadpool remains detached; his pros are all practical and have nothing to do with how being and doing good affects one's character.
