Mr.Panda
Let me tell you a story.
My brother has Aspergers. He is extremely intelegent, artistic, and creative. He lacks knowledge of basic social behavior, dislikes being touched, and has a negative outlook on almost everything. He is my older brother and he was eleventh grade when he ran into some problems with our private highschool.

The problems started in tenth grade when he grew attached to this girl and came off creepy when he reached out to her. He said nothing threatening, did nothing sexual, and went out of his way to do nice things for her. Looking back I suppose the overall effort of the things he did to make her happy would be what made his attempt to reach out socially taken in such a wrong way. The girl, although she didn't cause the problems, stood back as her extremely overbearing mother tried to cause as much damage to my brother as possible. She wanted him out of the school.

Later, in eleventh grade, he made a worse decision. He logged into someone else's account on some site and posted something outrageously immature and sent it to tons of people. It was stupid but something obviously done for group acceptance. I don't think he was bullied into it, I think he believed doing something like this would make some of the kids grow attached to him. He definitely didn't do it as a show of power or intimidation, but what he as a practical joke played by some friends together. Since he lacks basic social understanding, in this post he made a joke about rape. Not the best decision, although the joke was funny, sending something with multiple edgy jokes, one of which conserning rape, to ton of people runs the chance of someone along the line perhaps being offended.

Now the mother of the girl did her damage to my brother's image. They were trying to get him out of the school as fast as they could. They suspended him and had him seeing psychiatrists and social groups all over the place. But what tipped me off to what exactly what was going on was the psychopath test they had him take. They said that passing this test would basically end the problems, but once he passed it they only thought the test was taken wrong. Then it occurred to me that the school psychiatrist was the one making almost all the problems. They thought my brother was a psychopath.
(To be fair he draws pictures of animals with guns, mostly cats, but that's because he likes videogames and drawing cats. In reality he loves animals. He's a vegetarian for gods sake.)
Here's where I enter the story. You see, I'm an almost straight A's student in all honors classes. I'm loved by the teachers and the students unnanimously. I am considered one of the nicest kids in the entire school and one fourth of all the girls, and I mean that literally, one fourth of all the girls in my entire grade openly have a crush on me.

I scheduled a meeting with the school psychiatrist over a lunch period to settle the problems that had been running their toll on my family. My mom was extremely stressed, and my brother was getting behind in all of his classes. So the meeting started out friendly and half way through I asked him why he thought my Brother was a sociopath.
This took his by surprise and he said:
"Well sociopath is a loaded word and a serious accusation. That said your brother has displayed some characteristics of someone with in such a position. Now, this doesn't mean he's a bad person, this just means that this school might not be the right place for him."
Then I asked: "do you believe he is a sociopath?"
He said: "we are looking into all possibilities, but I strongly believe that to be the case, yes."
So I settled the problem:"well you see, if you're trying to out the psychopaths in the school you got the wrong kid. My brother here, he will not harm a hair on your head nor the image of your school. You see this kid, this kid has Aspergers. He's lost socially. He doesn't understand the consequences of his actions like you. The problem is, I do, and as it's become dreadfully obvious you've never dealt with a psychopath, so let's get this straight. First, my brother will not leave this school, he might be a liability, but I'm a loose end, and any damage he could potentially do to the school I will do tenfold. Second, this meeting never happened. No one will believe you, I will deny it to the gates of hell, and if you utter a word of it I will hurt you. And third, if we have any more problems with you, you will have problems with me, and you don't want to have problems with me. Do you understand?"
He was mad and called in another head of school. I denied everything perfectly and made the psychiatrist look like a corrupt idiot.

The purpose of this story is to show that while someone might seem to fit the criteria of a Sociopath or psychopath, until you have truly dealt with a real psychopath, the thought might sound reasonable or plausible, even when it's not.

The other moral is that sometimes labels mean nothing. Had my brother not passed the psychopath test he would have been considered a psychopath, but his personality would have been the same. Even if your friend somehow has AsPD, what would that change? He doesn't seem to need help, but the fact that he might have AsPD seems to make you feel like he needs some help. Let me remind you that he has lead his entire life so far and nothing has changed in him but the recognition of how exactly he might be different.

I wouldn't worry, he doesn't sound dangerous nor does he sound like a sociopath, but that said, what would it really matter. What would it change? And what, if he sought a psychiatrist, would be the desired outcome.

You post was interesting, I hope you the best.
