Christ teaches us to eat with moderation and that our hungers are forgiven. These hungers include revenge and retribution. Even if you are a sinner you are entitled to revenge without the need of a legal defense. This can be tricky as principalities can conflict with the individual's needs. In these cases, it is best to seek advice from a local priest and discuss what you seek forgiveness about. Are you trying to avenge a family loss? Do you feel you need forgiveness for your passion or lack of it?

Regardless of your situation, Christ can make you feel justified as long as you have obeyed all local and federal laws. After all, even Jesus himself sought retribution against Judas Iscariot. This is indeed man's condition after the fall. Revelation illustrates a return to innocence by the act of repentance.

Repent, avenger, for not believing in God's mercy.
