“The Narcissist actually HATES HIMSELF - and it is from this self-loathing that his hate for others derives.”
Spirited: Yes he hates himself, more precisely, something about himself which he perceives as deficient. This comes about because he (i.e., Cain) has compared ‘self’ to ‘other’ (i.e.,Abel)who appears to have been more greatly blessed (by God) than “self.”
To understand Cain’s hatred of self think of an ungrateful, selfish child who ‘hates’ and disrespects the gift he has been given because he believes he has a right to something better which has unfairly been given to Abel instead.
Though it seems paradoxical it is nevertheless true that underlying hatred of self is preference for one’s self to God and all others (narcissism). This reveals that ‘self,’ the self-deserving, autonomous, imperial “I” deserves something more and this is the seed of envy.
If ‘self’ is primary then ‘self’ deserves everything it can get. The Bible however, does not argue from a human-self point of view but from a thoroughly theocentric worldview in which mankind deserves nothing.
