The famous quotes from "Attack on Titan" include:

1. I have never understood why no matter how wise and reasonable the choice is, no one can do anything until the result comes out. Know what's right and wrong about it. In the end, all we are allowed to do is believe in that choice and try not to regret it.

2. Apart from you, I am not responsible for the lives of others. ?

3. Fight! For this I can throw my life and blood, no matter how scary the world is, it doesn't matter, no matter how cruel the world is, it doesn't matter, just fight!

4. Excuse me, does my son’s death contribute to mankind? Or is it a meaningless death?

5. I'm sorry, Allen, I will never give up again. If I die, I won't even be able to remember you.
