“God judges souls, not bodies. “
Indeed, and the question before us is, are the actions and speech of the ‘enfant terrible’ in this story due to his soul or his body?
I don’t totally know, of course, but I do know that there is such thing as evil and some of us are more evil than others. Also, some of us hide our evil better than others.
I am loathe to put evil behavior down to simple physical factors; God does not.
It’s like asking how much of a bad piano concert is due to the pianist and how much is due to the piano. Except we can’t examine either alone. It has not been given to humans to see every possibility and sometimes it’s wiser to refrain from assuming the worst when it is unclear. God won’t make a mistake; people can.
