There are some people that are in fact narcisitis...I don't know if it gets this bad. There are other syndromes where a person does not get born wi th natural instincts for being nice due to a problem in brain development....if caught at an early age and only if in an adult if you can make them beleive they might need some help. That is just my take on it. There are differend neurogbiological, and biochemical things that can be looked into as long as the person is willing...just my opinion of course.
