These people are not only comfortable in their megalomaniac skin, but go so far as to embrace the fruits of their narcissism as "moral."  Feeling that something is right or wrong is enough for them to go on.  

Anyone who assigns themselves the skill to be "the" moral or ethical arbiter based upon their own goodness and wisdom is but a few steps removed from the classical definition of a tyrant.  Without a God, man becomes God--perhaps a concept the Center for Inquiry is completely at home with.
