Attack on Titan
Levi Ackerman is humanity's strongest soldier, the blunt and battle-worn captain of the Survey Corps. He speaks in few words, but the ones he keeps come back to a single idea: you can't know how a choice will end, so pick the one you can live with. Below are his real lines, each tied to the arc or scene it comes from.
“The only thing we're allowed to do is believe that we won't regret the choice we made.”
“No one knows what the outcome will be. So choose whatever you'll regret the least.”
“Believe in yourself, or believe in me and the Survey Corps. I don't know which is right. I never have.”
“If you don't want to die, think.”
“This is just my opinion, but when it comes to teaching somebody discipline, I think pain is the most effective way.”
“Don't get me wrong. It's not like I trust him. If he betrays us or goes berserk, I'll put him down without hesitation.”
“Give up on your dream and die.”
“The difference in judgment between you and me originates from different rules derived from past experience.”
“A lot of times, you're going into situations you know nothing about. So what you need is to be quick to act and make tough decisions in worst-case scenarios.”
“The lesson you need to learn right now can't be taught with words, only with action.”
“Hange, whatever you're about to touch is probably poisonous, so don't.”
“If you hesitate for so much as a second, you'll be dead.”
“No casualties. Don't you dare die.”
“It's good to see that someone has the balls to go, but don't forget to do your damnedest to stay alive.”
