Maybe his possible early stages of alzhemier or dementia has diminished his judgement functions to the point where he is merely left with pure raw to dominate his personality with little trace of and . I am being partly facetious with this statement in case you can't tell btw.

Anyways, when you look at interviews of him when he is younger, he was easier to type and appeared to be more logical than ethical. I don't care what his type is anymore, his extreme overt narcissism overshadows his type anyways. He also looked like a covert narcissist when he was younger.
