OK, so then you think the entire system is corrupt, and you should reform it.
Selective rejection of laws based on your own personal morals is wrong in every circumstance.
Either you believe the system is just and you follow all the rules (and work through the system to changes the individual rules you believe are unjust), or you believe that the system is fundamentally unjust and you take drastic action to fix it. If you don't, then you're a hypocrite - you don't really believe that the system is unjust, you're just using that as an excuse to selectively ignore laws you disagree with.
