I'm not sure its okay for China to be maiming and killing protestors while trying to subjugate a city under tyranny,

The reality is that there are not okay things out there, and people often feel helpless against them, and will do things others will feel is not okay to try to get their message across when they feel the okay way isn't working.

And as a global people we should support those that feel, out of desperation, they need to destroy their careers or risk their own safety to try to help others. Its the inverse side of the coin school shooters and terrorism occur on - both are driven to extreme action, but one is sacrificing oneself to try to help others while the other seeks only to destroy for selfish egotism. Both are indicative of systemic issues that need addressed.
