I'd say the appropriate read there is to slip the word "unjustified" into a few key slots. The view is nearly impossible to avoid in context. How do you see society surviving if the prevailing view is that anyone with a different belief is trying to bring on the end times? To the point where assassinating political opponents is justified?

It would bring on the end of a society. It might well happen in the US case, they've been heading in a pretty dangerous direction rhetorically. If we take the Soviet Union as a benchmark they probably have a long way to go but that sort of journey seems unnecessary and stupid.
