I've always felt that if we do, in fact, remember those who went to Hell, we would see it in the same light as God does, seeing the justice of it. I don't know that I could prove it by scripture, but I believe the condemned will also see the justice of it.
Isaiah 65:17 says "For behold, I create new heavens and a new earth; and the former things shall not be remembered or come to mind." Which reinforces your idea on the matter.
