Deleting Completed Stories?

So I read a few of my old stories and realized I can make them so much better than they are right now because I rushed them a little. So I don't want to have to keep editing them and none of my old readers know I changed it since they unsubscribed from them. Also if some of them do come back and read the old story, they will be confused to why some of the characters change or w/e.

So does mibba care if you delete old stories and remake them? Have you ever done this? And how is life :)? (Just curious)
