Sometimes we have a lot of useful words but have trouble putting them together. In the current case, however, they speak loud and clear. Let’s review the vocabulary and its implications:
Extremely anti-social views and behavior, coupled with a lack of conscience, are evidence that a person is suffering from sociopathy. It’s hard to tell if someone actually lacks a conscience, but anti-social behavior is easy to spot. People who habitually flout the laws and mores of their society, and who are, in fact, against those laws and mores, are behaving anti-socially. This may even be accompanied by misanthropy, which is the hatred of other people.
But just because you hate other people doesn’t mean you can’t love yourself. Narcissism is just that — excessive vanity and admiration of self. And of course, egotism follows, for surely such a fabulous person as oneself will be completely selfish and self-absorbed. It’s the mindset of the spoiled rich kid — I want it, give it to me now!
