Quote from : Puella Magi Madoka Magica, Vol. 03 Book

Madoka: I'm always... making somebody else fight for me. I can't do anything... Does that make me a coward? Kyōko: Why do you gotta be a magical girl? Madoka: "Why"...? Kyōko: ...This work isn't about playing around. When the job's about putting yourself in harm's way, the only ones who do it are the poor slobs who don't have any other choice. The others who are surrounded by loving families and have the whole world ahead of 'em... the idiots who become magical girls on a whim... They're the ones I can't accept. I just wanna crush 'em! ...Someday the time may come when you have your back to a wall and you gotta fight. You can think about that stuff when the time comes.
