I think when dealing with these types of people being harsh is very much warranted. They earned a harsh response based on their general behavior on this forum. I could easily be as harsh or more if someone managed to piss me off. So you're tone was actually justified and you shouldn't be too harsh on yourself.

You do have to be very careful not to implicate anyone who isn't at fault, and that includes unemployed disabled people including autistic people. That also includes people with personality disorders who are regularly thrown under the bus in a world where the majority Them being unemployed or poor or what have you is as much the fault of society as it is their bad attitude - no one should be poor in an ideal world. That's all I wanted to make clear. That being said there are plenty of disabled people including autistic people who are just arse holes, and it's fine to call them that too.

I sincerely hope we find a way to effectively treat narcissism and other personality disorders one day. It causes as much suffering to the individual in question as it does the people around them.
