Am the first spiteful loner here.
You are the Spiteful Loner, the personality type that is most likely to go on a shooting rampage. In high school, you were probably that kid who wore all black and who sat alone in a corner of the lunch room, drawing pictures of dead babies. You are a rational person and tend to hold emotions in very low-esteem; not only that, but you are also rather introverted, meaning you probably bury any emotions you feel deep inside yourself, like all of the bodies in your backyard. Combine these traits with your dislike of others and your brutality, and it seems that you would be quite likely to shoot innocent people in a rampage. Most likely, you also have low self-esteem. Hell, I get low self-esteem just looking at you. This is only yet one more incentive to go on a shooting rampage, because you wouldn't care if you died as a result. Granted, you probably haven't gone on a shooting rampage and probably never will, but all the motivations are there. All you need is for someone to push you over the edge, calling you names and belittling you. Like me. But don't shoot me. I have a 101 mile-long knife, you know. In conclusion, your personality is defective because you are too introverted, brutal, insecure, and rather unemotional. No wonder no one hangs around you, you morbid, cold-hearted freak!
To put it less negatively:
1. You are more RATIONAL than intuitive.
2. You are more INTROVERTED than extroverted.
3. You are more BRUTAL than gentle.
4. You are more HUMBLE than arrogant.
Your exact opposite is the Televangelist.
Other personalities you would probably get along with are the Capitalist Pig, the Smartass, and the Sociopath
