Interesting reading, but hard to have sympathy when he causes suffering for so many.

I also don't think changing his behavior is within reach. His narcissism prevents him from growth and, like the scorpion in the tale, he can't help but sting.

Thanks. FWIW I wasn't trying to imply that we should have sympathy for him.

My only point was that so much of this suffering, both for himself and others, could be avoided but for his choices and flaws.

I don't think it's so clear cut. The problem is that his personality defects have allowed him to be influenced by people who are truly malevolent. Those people lurk more in the shadows and so avoid the condemnation that they deserve. Trump is their obvious useful idiot with the target painted on his head.
