I was watching an old Stargate episode where a character called Linea (who was previously a genocidal mass-murderer) loses her memory, and becomes a lovely new person. Then her memory comes back and she has to fight between her new self and her old self.
In cases of temporary memory loss (say for a year or so) where a person goes on with their life, and continues to develop as a person, could they have a clash between their “old-self” and “new self” once they regain their memory?
For instance, if they feel in love with a black person and then remembered that they are a vicious racist. Or if they were nice to everyone, then remembered that they are a cranky git.
The OP wasn’t talking about repressed memory, but recovered memory. You certainly can recover memory, and retrograde amnesia is a real phenomena. Repressed memory is bunk.
