"Do you accept that there are people who deliberately stoke their own anger and feed it like some growling beast within themselves."

Not really, no.

"Why do people go looking for arguments, or in some cases violence (not boxers, but guys who go out to get drunk and get dangerous)"

This seems to be a rhetorical question with no right answer, and has no bearing, to my way of thinking, to the original question posed here, which was, as I read it, can angry behavior be defined as an addictive behavior.

My answer to that question, is no.

As to your last post, I'm pretty damn baffled at what your agenda was for starting this thread.

I took your initial question at face value. I don't think you and the others here with what looks an awful lot like pseudo-radical behaviorist tinged popular beliefs about anger, wanted to hear or likely even discuss the answer I gave.

C'est la guerre.
