There's a qualitative difference between sympathy and empathy.
ASD might be more selective in these matters than NT's. This is not only scientific theory, but i have witnessed 1st hand. NT's supposedly have more mirror neurons. Which means they are more naturally inclined to express sympathy/empathy reactions to a given stimulus, atleast on the surface body-language level. We on the other hand, might appear more indifferent, stone faced, unreactive to the same stimulus.
