You would condense the psychobabble by eliminating a category. Actually, that is precisely what a significant faction of the shrinks (APA not AMA, to bisect another hair ;-)) want to do as they redefine their DSM. The proposed DSM-5 reduces the number of personality disorders to six from ten. The distinction between narcissistic and antisocial personality disorders remains intact. The shrinks don't use the term 'sociopath' so I think we can agree to broaden the definition to include both disorders.

I prefer to simply define the jackass occupying the Oval Office as a miserable, misanthropic motherfucker (just to get my alliterative licks in. ;-))
