Aizen: Then let me ask you this. When did you think that I wasn't using my Kyokasuigetsu?

Sosuke Aizen: This world was never about truth or lies. There are only hard facts.

But for the powerless who make up most of the world, facts that act against them are the only truths.

Sosuke Aizen: Believing is the same as relying. That is something the weak do.

Sōsuke Aizen: Treachery you can see is one thing. What is truly dreadful is the treachery you can't.
