Emotion + Apathy = ?

Sociopaths do a lot of heartless everything.  What would you call one who can't tolerate wrong doing, to the point where they get very upset?  A reader writes:

I'd like to hear your opinion and the opinion of your readers on something I've been realizing lately. It seems to me that I am a very unique person, and anomaly. I seem to be a borderline sociopath, capable of feeling at both ends of the emotional spectrum. I've always been extremely intelligent, viewing the world in countless ways and expressing opinions that often earn contempt from my peers, simply because they are too narrow minded to understand my views. As such, have had trouble connecting to people around me, with most of my friends being simply people who pass the time. I've always thought that people were insufferable, cruel idiots, and yet, I am genuinely charismatic and enjoy the company of people. (The ones I can tolerate, anyway) I've only ever met one person who I thought of as my equal, and she was just as intelligent as me, which I found strange, as I thought that anyone with my level of intelligence would naturally be a logical sociopath, but she wasn't even close to one. 

When I am around people I care about, I am one of the nicest people in the world, and will go out of my way to help them, so long as my own needs are met first. However, when I'm around people I hate, or I here about criminals in the news, I am filled with a burning rage, and often fantasize about torturing and killing these people. If I ever had to kill someone for the right reason, I don't think I'd hesitate or feel even a shred of remorse. I have very strong morals, but I'm also flexible with some opportunistic actions, and I don't believe that any action is inherently evil. Rather, it is the circumstances and intent behind the action that are relevant. 

I believe that sociopathy is human nature, as all children act like sociopaths before they are taught to care for others, and while my mother made attempts to teach me empathy, my logic took over and made me ask "Why care for those who don't show me the same respect?" I don't go out of my way to manipulate people, but when I find it necessary, it is usually fun. I have my own very strong personality and I don't act with different ones as most sociopaths do, but I have a great understanding of the human mind and how to manipulate it. It just seems that, while the main focus seems to be total, emotionless sociopaths, I have an almost perfect balance of emotion and apathy, and I was wondering if anyone has ever encountered something like this before? And what do you think?

M.E.: This is interesting. I think a lot of people who are very smart naturally gravitate towards a more open minded, amoral, even pseudo sociopathic mindset. There are exceptions of course, like your intelligent friend. I think the thing that makes me least think you are a sociopath is that you want to kill criminals that you hear about on television. Why would you have such a strong reaction, if not moral outrage?

Reader:

I agree. If I were truly a sociopath, I wouldn't have such a strong reaction to crimes and immoral actions. It seems to me, then, that borderline sociopathy is a natural by-product of intelligence. In a situation like mine, it seems like it would be incorrect to even label it as a mental abonormality; rather, it is just another worldview that the common, narrow-minded empath would label and 'wrong,' as uneducated societies have always done to those who are different.
