Which type of behavior is the "disciplined" badge trying to promote?
Why users who deleted their own posts, which had a score of at least three, would get a badge?
I am contemplating deleting my answer to a question on Programmers.SE because the original question has changed so much that my answer no longer applies. I have four upvotes (some of which I have received since the question changed) so deleting my answer would earn the badge. I have not deleted it yet because it helps show the confusion that can surround the entire topic of the question.
I find deleting my own answers wrong especially if others have voted on it, up or down. I feel there should remain a record of what people responded to (especially if it was downvoted, then people can see what a wrong or unpopular answer is).
I can see that deleting a high voted answer takes discipline (do you lose the associated rep?), but I don't get why it is rewarded with a badge.
