Why is Abed so likable?
Data, for his lack of intuitive understanding of the human condition, had a clarity of purpose and perspective that emotional creatures lack. He is a flattering mirror, he makes us see a noble, uncomplicated version of ourselves.
To answer the question about morality, morality is logic applied to emotion.
I really like this answer. Very insightful.
Data enables us to see past the subjective reality that emotion can present, and helps us see the truth in the world around us through a dispassionate perspective.
You're right. Abed does the same thing. I never thought of that.
