No, this is not correct. This line wasn’t a distraction or red herring. The point: If you can tick off all the criteria for “Malignant Narcissism” simultaneously for both Hillary and Trump (and probably a whole host of other politicians, if we want to be honest), and then assert Trump has the problem and Hillary does not, then it tends to show TDS is alive and well.
Notice: it is not agreeing with the assessment in any way for Trump or Hillary. It’s a test to see if his world view is internally consistent.
It wasn’t a fallacy.
If anyone is asserting that Hillary is ethically better than Trump, then they are wrong. I believe Trump doesn't like people dying, Hillary's a little more comfortable with killing people, a total war hawk, making her more evil than him in that regard. Trump pulled back a strike on Iran because of the body count, that never stopped Obama and wouldn't stop Hillary for damn sure.
