You're right about me declaring Gruden a bad person.
I abandoned my usual practice which is to not judge others because we can never know the entirety of one's actions and without knowing this, it is impossible to know a person's true nature.
Also, I believe that there are ambiguous people who even if you did have knowledge of the entirety of their actions, would be difficult to classify as either good or bad.
So I should not have judged Gruden. I can only guess as to his character.
