I personally would want people who I know and love while I am alive to forget me and move on with their lives after my death.
It’s like I would be happier in whatever is in the after life to see the people who I cared about happy with their lives, instead of getting sad whenever they remember me or worse yet, remembering me on yearly basis after I am gone.
I genuinely find it very illogical and selfish for people to want everyone to never forget them long after they are gone, especially due to the pain that come with memories.
That is why I am curious about the reason.
Not as an answer to the question, but on the same note: Maybe people could be made forgotten by everyone else upon their death. Like hard-forgetting they ever existed, erasing them, just for the sake of not having to bear the burden of loss.
