I know there are typical things which are considered unpleasant that people with ASPD may be inclined to derive temporary enjoyment from, such as a making other people angry and despondent, causing abuse, doing too many drugs, switching jobs, etc. However, what about insignificant, odd things such as vomiting (especially when drunk), getting bruises, starving, feeling overheated, being exhausted, passing out, getting cut, seeing blood, throbbing pain, being disliked, and other typically unpleasant experiences?
If you find this to resonate with you, well, one could cite a study you may be aware of which proved that people would rather be electrically shocked than to experience consistent boredom. I can definitely say that has been proven within my life in... scaringly accurate ways.
