If you believe in manners, then gifting bad gifts is bad manners.
That's why Santa keeps a list of Naughty and Nice People. As a Consequences of their own actions.
A Green Giant sized stocking full of coal would be a nice gift to someone who had been good all year and just what they wanted and needed to keep from freezing to death in Siberia.
To some budding Dennis the Menace to Society who had been bad all year and thought he deserved a new Bicycle, stole one but wanted another one for Christmas, a stocking full of coal dropped from Santa's Slay at 5000 ft in the path of his Ill-gotten chain would be a bad thing, but might be just what he deserved.
The flow in Behavioral terms is Stimulus - Response - Consequence:
Stimulus - You poke me in the eye with your right index finger for no reason.
Response - Ouch! That hurt my eye when you did that.
Consequence - I grab your right hand and break all your fingers.
As a result the likelihood of you doing it again is greatly reduced. Ideally, and goal of my Response, that the behavior is extinguished and never repeated. That takes the ability to associate your own inappropriate behavior with the consequences delivered. You have learned.
Stimulus - You take your left hand and try poking me in the other eye.
Response -- Oh no you don't... I block it like Moe does Curly on the 3 Stooges.
Consequence - I break all the fingers on your left hand, too.
If you could not associate your own inappropriate behavior with your broken fingers, you are a slow learner but will not be doing it again with broken fingers. If you try it again once they're healed you will eventually learn or your fingers will never be the same.
That separates those who can learn from the experience with minimal discomfort and go on with life without repeating the behavior from those who cannot learn but are frustrated sufficiently by the painful experience and don't try it again.
That is the Basis of my Behavior Modification Programming of Demonica to address unwanted sexual advances from users though an unpleasant, unexpected response to the stimulus and has a 100% success rate.
