According to him, ever since he was a kid, he's been unphazed by violence and things that would scare most people. He would think about these things with thought-provoking interest, but emotional apathy. He was a juvenile delinquent simply because of his mischievous need for thrill, but got away with what he did most of the time, because he was so clever. To this day, he will tell you that he just doesn't care about humanity in general. His attitude is evidence of this. However, he does care about certain people who he chooses to and he would do anything for those people. He still has that feisty-side, but he's matured and learned to use logic and common sense keep in in control most of the time. He is very ambitious and wants to succeed. Getting in trouble is counter-productive.
I'm not sure what to make of it. I've read from some sources that say sociopaths are incapable of emotion at all, but that's not true here. He definitely experiences anger. He definitely likes laughter and fun. He definitely cares about certain things. It's not like he's a robot or something. However, he does fit the mold of most any online (which I know is not reliable) description of a sociopath. I've always wondered if his lack of fear or insecurity isn't what's helped him in life to rise beyond where the average person might fall.
