The one line in the film Henry refuses to cross: she won’t remember, so does that make it okay? The whole arc is built to answer no. A party who cannot keep a record is a party who cannot hold you to account for what you did with it.
This is the ethics of statelessness, and it points straight back at the root. A witness-less act is the oldest rationalization for harm — so an AI that forgets by design has to be held to a higher standard, not a lower one. Forgetting is not innocence.

Sharpened to 'memory asymmetry is power asymmetry.'
drift: Does 'forgetting is not innocence' overclaim?
