What advice is being given here to make the world a better place and avoid negative consequences?
The short answer? Yeh, you are VERY wrong in your thoughts. Make the world a better place. Help out the victims. Vote judges in that will give more than a slap on the wrist. There are lot of things to do. Dwelling on dark thoughts will infest your life and you could end up just like that loser vigilante this is written about. The LAW enforces the law. YOU will go to jail out of stupidity.
