I don't follow what you mean about context, you brought up a bad example and you're moving goal-posts.

There have been numerous revolutions with positive benefits to the world at large as well as to the society/culture in which they took place. I would chance to say that the majority were net-positive. If you find yourself scared of revolution, you should maybe take an introspective moment and ponder why the poor and downtrodden of the world (or just in your own country) would consider you their enemy.
