> you think the entire system is corrupt

I do.

> you should reform/replace it

This is a way to reform it. If nobody obeys a law, is it really illegal? It's more like a custom.

> Selective rejection of laws based on your own personal morals is wrong in every circumstance.

So if your so called authorities passed a law saying you're required to participate in some atrocity such as genocide, you'd do it with a clean conscience? Okay.

> you believe that the system is fundamentally unjust and you take drastic action to fix it

I don't have the power to do so. Also, people who try "drastic" actions are called terrorists.
