In "Altered Carbon", a character that has lived for hundreds of years destroys an instance of his self in order to prevent the upload of a mind virus into a backup copy of his self. In doing so, he loses a few days of experience.

Is that situation utterly contrived because he destroyed his mind, or are you insisting on a limited definition of self?

(Let's set aside the part where there is mind replicating technology but no snapshots or version control)
