Yeah, I mean, he definitely did some things that were Not On. But sometimes I feel like he shouldn't still be carrying it with him? I mean, on a meta level, not a character level--I have often been convinced in fic, and in canon there is his awareness of his actions--but I just think sometimes, my god, would I blame my brother for being dumb and mean when he was nine years old? And then I think, no, we would all let it go.

You clearly are not from my family. :-) We never let anything go. My little sister (Vicky) can still, at the drop of a hat, be induced into ranting about how my parents forced her to miss performing her third grade holiday play so we could extend our Christmas visit to relatives by half a day. I can do a similar rant about being stashed in an after-school daycare program until sixth grade just because my parents were afraid Vicky would get shirty if they let me walk home after school while she was still going to the program... even though she had friends there and I was the only person my age there for three years.

See? *wry*

More seriously, I am certain Peter, Susan, and Lucy forgave Edmund very quickly. I think it took Edmund significantly longer to forgive himself, and even when he let the emotional immediacy go, I am sure he kept the facts readily to mind, as a reminder and a warning.
