I believe that one of the core concerns that Asperger's have in concern with the majority of the population is empathy, but I have never been content with the notion that we are simply just born ignorant to this. First of all, empathy is not something that can be easily learned and practiced throughly, it while requires alot of dicipline and selflessness. That's why even though "normal" people seem to have it, they don't show it very often.
Empathy is essentially a form a prosocial behavior, in other words, you do positive things for others at the cost of some of your own personal freedom. But there are many motives for why people might chose to be empathetic, and some of them aren't so noble.
One reason is because we would like to believe in a "just" world, where the good are rewarded and the "bad" are punished. However, an inteligent person eventually will eventually realize that good and bad are subjective, and thus the real reason some are empathic in this regard is because we want nice this to happen for them or people like them.
Another reason we may chose and not chose to be empathetic depends on the person or the victim who is in trouble. Would you guys help someone that you didn't know if he/she was similair to you in regards to your appearances and core beliefs? Most likely you would, however if you turn this around, would you help out an individual if he/she was different or evenly starkly dissimilar to you? Unfortunatly no, and this is true for everyone, including aspergers, because it's very hard to relate to someone whose different, useless you're forced to share their experiences (walking a mile in someone else's shoe) in order to empathise with said individual.
Another very obvious reason we do nice things to other or attempt to understand how our action affect others is because of religious motives. Okay, I have to say this but does anyone HONESTY think that the fear of eternal damnation outwards the "moral" duty to do the "right" thing in order to ascend to heaven. Before I continue, I am not trying to tick any one off, and if someone has a different perspective about this feel free to respond about it.
In a nutshell, everyone knows what we are taught to beleive about heaven and hell, but there are motivations to be empathic to others. However, this is in reality an selfish reason to be nice to others, because we want good things to happen to us when we die, or rather, that's what we're told.
No one's evil for not being empathic if they aren't sure how to be empathic, but let's turn this around once again. If empathy is so important to neural typicals and they should know by now that asperger's lack it, why haven't they attempted to teach us it? The answer is that have, but it doesn't work for Asperger's because we need a different means of learning how to be empathic. People use to belive that blind could never read, by brail was develop so that they can. Those who are deaf are taught sign language so that they can communicate and understand others.
For me, I had to use self role playing, in other words I create potential situations and act out how I think both parties would behave towards one another. In other words, I talked to myself. Ha Ha, right? No, there's nothing funny about it because neural typicals do it all they time, but they are afraid of being called schizoprhenic, which is completely absurd, especially if you knew that processes that it takes to diagnose schizophrenia. Plus, aspegers are known to do this anyway, it's natural for us to verbalize are thoughts, so why not use it to help ourselfs.
Anyway, don't assume that your thoughts are so different from everyone elses that your hypothetical situations will never add up in the real world, because everyone thinks about how there are percieved by others, or how they would feel if someone they knew did something. This actually works, and it forces you to become more aware of how you actions might have or might affect others. Now whether you chose to be empathic once you've learned how to grasp the concept is up to you, but do it for the reasons that you feel our the better reasons, which aren't just the one's I've included about.
