I'm with much of what's been posted.
Ain't no halo here.
I have a long fuse, with a big bomb at the end of it.
I don't know to what degree AS affects my vengefulness. I follow the old Chinese proverb: Revenge is a dish best eaten cold. Which means, for those foggy on the abstraction: if somebody has wronged you to a degree worth revenging, don't lash out in anger right away; cool off your anger first, think about it, and if it's still worth it to you to get back at them, plan it well and execute it calmly and coldly. Better chances to succeed and make your point that way.
Aspies may be better qualified to employ this principle given our logical bent.
I have found, as one poster mentioned, that in choosing not to lash out in anger, and letting myself cool down before entertaining thoughts of revenge, I find that I wind up understanding the flaws in the human who wronged me, to the point where I let it slide.
I look at it this way: I never start s**t with people. So if somebody starts s**t with me, they must have underlying issues or defects beyond their control. In a way, striking back at these people is like hitting a cripple. Not every time - if provoked badly enough, I will strike back.
The other factor that tends to keep my revenge in check is the risk factors associated with retaliation, which are many. Most times what I want to do to people is illegal, carries significant prison time, and puts me at physical risk, as well as escalation or retaliation by my enemy's allies. These factors often make revenge not worth it.
