Recovered momory cause personality disfunction?

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.

My instinct is no, but I was just curious.

Sorry this should be in General question. Sorry.

Since the whole concept of recovered/repressed memory has been found wanting, there ain’t a lot to answer this question with.

Thats what I get for watching too much TV.

I understand also that when twins are born, it isn’t necessarily the case that one of them is evil.

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.

Just what we’d expect an evil twin to say!
