Move through life.
In the end, it's not about what anybody else has done or what anybody else has done to you. In the end, it's only about what you have done, and what you have done to the people who have crossed your path.
On the micro level, justice is not about courts and laws and society, it's about one's own actions. If someone wrongs you and doesn't make it right, that's about them. If someone wrongs you and you wish harm or retaliation upon them, that's about you.
If you wrong someone, it is your responsibility to make them right. If someone wrongs you, it is still your responsibility to not make it difficult for them to make things right. If they continue to wrong you, then it is their karma, and their karma does not concern you.
This applies to each and every person who crosses one's path. This, I believe, is part of basic human law. Social law, where courts come in, is when two parties cannot agree, and both believe that they are right.
Passion should never overcome compassion.
A rights-based society without responsibility leads to rampant self-righteousness.
And my vulnerability has nothing to do with anyone else.
