One of the major takeaways from Mary Trump& #39;s book:

Yes, Trump& #39;s as profoundly disordered and in just the ways we described, as we all see daily. Specific diagnostic labels may matter less than grasping the core of his character pathology: a lack of conscience combined with...

...an insatiable desire for adulation and power meant to prop his eternally fragile ego.

The view that we can& #39;t recognize and name this pathology w/o 1:1 exam is untenable, as is the position that Trump& #39;s character is not pathological, merely bad.

The latter would imply that...

...the profoundly disturbing behaviors we observe on a daily basis are within the norm.
We& #39;d be led to believe that the lack of empathy & compassion, the instrumental and sadistic (mis)treatment of people, the self-obsession, rageful egotism and lack of self-control are normal.

To be sure, many -- indeed too many -- people do believe this is the case.

P.S. And that is not even mentioning his constant lies and tenuous grip on reality.

P.P.S. Lack of conscience = psychopathy.
