Part of my symptoms of OCD are moral (not religious) scrupulosity. So, moral issues, thoughts and compulsions have been quite common for me. However, research suggests that people with OCD and not necessarily scrupulosity are more morally sensitive than the general population. As Medical News Today reports:
Morality problems cause much more worry for people with OCD (obsessive-compulsive disorder), compared to the general population, researchers from the Hospital de Mar, Barcelona, Spain, and the University of Melbourne reported in Archives of General Psychiatry.
The authors added that their findings prove that patients with OCD are much more morally sensitive than people without the disorder.
