This thread has made me think about the question of empathetic responses to movies. The underlying question in my mind has to do with the fact that the emotions and physical pains are fake in that context. An accurate empathy would absorb the underlying artificiality of it along with the superficial expression if it were accurate and direct empathy.
Most people place the context of movie as a distinct category from real life. They can eat popcorn and watch suffering, but when confronted with suffering in reality their reaction is much more involved. Those times that I have had a strong response to violence in a movie is based on the assumption that it is a representation of something that has at some point been reality. It is a symbol of the real. When there is a strong reaction, it isn't my version of eating popcorn suggesting a complete melt-down in reality, but rather a lack of distinction between the two.
I was also wondering about the issue of conflict. How would someone with strong empathy relate to conflict? Would they tend to identify with the other person readily enough to be on their side as much as their own? Would the negative emotions conflict instills in others be a de-motivator to initiate or sustain conflict? Or would they reflect it back and match the level of conflict with which they are presented?
