Yes he is severely mentally ill. And unable to form normal adult relationships.

[Irish_Dem]

It is all transactional.
And all about him.

There is no love, liking, respect, caring, compassion, support, etc.

People are just props in the movie that runs in his head.
He is the only one who counts, the star.
And people are only useful in terms of what they can do for him.

This is a classic narcissist and psychopath.
And now he has dementia on top of it all.
And I assume he is still a drug addict.

This is a man who should not hold any position of responsibility.
