Of course. Much was achieved and that included systemic harm to those around him.
He was a man who never understood that he was prioritizing things and accomplishments over people. I suspect empathy didn't factor into the calculations in his head.
I'm not damning him here. Having been him to a degree, I can testify the distance to working empathy isn't trivial. It gets crossed with a great deal of time and difficulty. Further, I see signs of pronounced OCD which may complicate his challenges in ways I may not understand.
These things are good to understand. So is the harm he brought to people who trusted him.
