Also within neurological structures you will get lesions in some brains making some people have less distinct emotional memory of their own experience so are less ego driven. Then you also have others who may have lesions in area's that can range from anything from mild to complete lack of empathy. There are a multitude of "black & white (noise?) thought" processors out there too .. It really is deep when you get into the brain mechanics.. I hadn't heard about this bit of research.. thanks! Runs off to search engine cackling..

@Nickbeee I am very interest in research on the brain. it is where it all begins. Its where we all begin...

Thanks lol !

I do not care why a person refuses to do harm . Their reason is as valid as any one else's. The decision to not harm is a positive aspect of ethical behavior based upon religious belief. Guilt is one form of ethical responses we feel when we have done something wrong or are about to.
