1) Karma changes have not historically disappeared when the comments or posts responsible for them have been deleted, as far as I know.
2) Deleted posts can still be accessed if you know the permalink, and the comments remain in place too. Deletion only makes the post inaccessible through certain avenues like the sidebar.
Question: Can negative karma be eliminated by merely deleting a negatively rated post?
Hm, though that might be a problem if the post is already quite old or has a lot of comments...

Thank you.
