"All of what you said in your first paragraph sounded like excuses for why you plan to keep looking at people as disorders."
Well, not all...You seem to have glossed over this part.
"Eventually I need to get to the ASPD ideal of dealing with each person individually. For now, being able to identify group behaviours and testing reactions against them is the first step towards greater flexibility later."
"You already put too much thought into it instead of just going with the flow, and you are in no position to make others suffer for your poor decisions."
That's exactly my point. You HAVE to put thought into it at the beginning. Developing a skill requires conscious awareness of the effect exercising a particular behaviour has and continually modifying it until it becomes second nature and you can just "go with the flow." ASPD's do this naturally. It is a talent honed through environmental training on top of genetic predisposition. Others have to learn that skill over time.
"You can't win this way. You already fucked up too much. And IF this guy was a psychopath, you going out of your way to ruin him is only going to tickle his fancy. Seeing others work hard at retribution is a huge ego booster. It means they got to you, and they are all about being someone's inspiration. His fall will come, and it will be all from his own doing, not anything you did, or anything other pissed off people did. Stop deluding yourself into thinking you can have any form of power in this."
Your warnings are well noted. The good news is that I really have next to nothing to lose. He can get me fired (good luck to him), and I will have a job waiting for me with a 50% pay rise. It'll be worth it.
