When we seek retribution, we may find satisfaction, but we rarely find peace.
When we seek vengeance, we might find justice, but we rarely find healing.
When we seek to tear down another to build up ourselves, we are building on sand and our house will surely fall.
There is only one right way to heal an injury from another. That is to find the wholeness within ourselves that was never injured, and return to it.
When we seek to hurt another, we not only hurt them, we hurt ourselves. And we hurt ourselves far more than we can ever hurt another.
Has someone done wrong by you? Start by forgiving yourself for being involved, take better care of yourself, and examine what within you is holding that energy active. There is always some kind of energetic pattern that created the situation to begin with.
This is not to say that you should keep the person who wronged you in your life, of course not. Yet that is exactly what we do when we seek retribution, vengeance or harm upon another.
Making peace with ourselves is a far more effective way to find the healing and wholeness that we truly seek.
