I wouldn't say that. It's always better to remember a good friend. But you're right. His happiness is the most important.
[And that's a large comfort of him going home: that he won't be remembering any of the horrible things he endured while in Luceti. Especially everything related to his death.
But speaking of death, the second part of the message gives him pause - as it makes him very sad. He knows a lot about the future, after all. He knows that he himself will only live to 66 - which could be considered to be old, but not really what Souji has in mind. He doesn't know how long Sokka will live... but it has sounded like he'd be gone by Korra's time]
I'll see him again someday. And we're going to have a lot of time together as friends.
