I have not enjoyed reading this thread.
It brought up all the old stuff, and I am upset to realize just how intense and deep the hatred still is in me. I thought I had moved passed that, but obviously there is a huge suppressed part of me that is consumed with desire to terrify, mutilate, and break anyone that seeks to hurt or dominate over others in any way...
I had similar, for the biggest gang fights I have been involved had to do with this one guy and me.
I never realized why did so to pick me for such, never did anything bad to him at all.
On the other side, the chap had lots of trouble with a lot of other people and have been expeld a few times from a few schools.
Later, in changed school and guess what? After he cause trouble on the other school, he changes school to my new one too...heck so much for luck.
The fight carried on for ages and affected friends and lots of other people, even as we aged, he never let loose of that and whenever he was in bigger number he would chase me...but never alone.
Well, years passed and I had the same feeling you described, but had a good sense not to pull it up and actually do it.
But one thing remained in my head, as to why the guy would waste time doing such things.
I knew he had a tough life, his father committed suicide when he was young and he had plenty of other personal/family problems already.
About last year. some 20 years after I had any contact with him or the town at all, I dreamed with him and on the dream, we were very good and close friends.
There he was showing me some paths to take on a ground road. I woke up a bit annoyed by such as I haven´t thought about him in ages.
A week later, a friend from the town I used to live told me that he had developed a hardcore type of cancer and struggled in pain and faith for life for about 6 months before he collapsed and died.
Such news struck me really hard and made me really super sad for quite a while, it still does as I type. Maybe in my youth I had no knowledge on how to actually deal with such and just maybe there was something I could do to make the story different. What I have left in my heart is the feeling that we are, somehow, very great friends. I can´t really think of us as arch enemies as we were in reality anymore.
