Marking an article read keeps the thread tree intact and I might chose
to look at the articles that are marked read.

Killing an article, in my newsreader, tends to flatten the tree more
than I expect. Because there are "missing" articles in the references
list posts below the killed post get displayed linked to the next
avaliable message up the tree.

The difference between the two display methods is usually small but
someone used to the tree display should be able to tell the difference.
Caring about the difference is quite another matter.

Also killed messages are not downloaded and that's faster.
