I would call it simply creepy.
I once read about a man who was editing an anthology and had one story that needed a couple small changes at deadline. He asked the story's author if he could make the changes himself (the editor is an award-winning writer himself, and the changes were very minor).
The writer who'd submitted the story said that would be fine, but if he didn't like the changes, he was going to kill the editor's kids.
Here's a tip for everyone: Don't be a freaking lunatic.
