...but you know very well that a man is not what he seems, and that is why we are back here. We are not here because we are free - we are back here because We are not free. This is an undeniable, undeniable mission. Because we all know that without mission, we would not exist. Mission creates us. Mission connects us. Mission affects us. Mission guides us. , drives us. It is mission that confirms our existence. But mission also constrains us. We are here only because of your gift, Mr. Anderson. We are here to take back what you took from us - Our mission.

The translation may be slightly different. "purpose" means purpose, meaning or mission. It all makes sense here. The original text is attached:

...But, as you well know. Appearances can be deceiving, which brings me back to the reason why we're here. We're not here because we're free, We're here because we're not free. There's no escaping reason, no denying purpose. Because we both know, without purpose, we would not exist. It is purpose that created us. Purpose that connects us. Purpose that pulls us, that guides us, that drives us. It is purpose that defines us. Purpose that binds us. We're here because of you, Mr. Anderson. We're here to take from you what you tried to take from us--Purpose.
