"... does justifying one out of pocket thing tend to lead to many inevitable downstream justifications?"
I was just really addressing around this last blurb. I'm not advocating for either violence or these crazy people. It would seem the continued justifications snowballing or not being acceptable would be an it depends issue. I'm not looking at it from the philosophical or psychological type of standpoint you seem to be at depth.
I would assume it depends on people's tolerance for outcomes and their camps they fall in. Seems too many variables. So, it depends. That's all I'm saying. I should probably spend more time thinking about your overall ? Though. Hopefully these whack jobs don't gain traction but this seems to a Bill Gates type of ilk
