There are only two acceptable outcomes: a successful mission or death.
Carlita: Atlas is a lifelong commitment, but it's for something greater than oneself, and once you give yourself to it, you're in it for as long as you can be of use. Because going into each new mission there are only two acceptable outcomes: a successful mission or death. You don't stop until you reach one. That's just how it is. If you're a true believer, at least.
Harris: Guess you're not a true believer then. Otherwise, why would you be here?
