A person who has no self esteem will not feel angry about being abused. But when that person finds anger, they have found that they are worth something to get angry about. Anger about abuse is equal to valuation of your person. Anger is a normal, natural, and healthy response. There is nothing wrong with a person who feels anger after being victimized.
Anger is a sign of healing and the reclaiming of self esteem.
With this anger, many victims obtain a need for justice and vindication. Ideally, it should be the place of the criminal justice system to provide victims with a safe, legal option for retribution. When a sentencing a perpetrator, the judge should consider the needs of the victim to focus their anger and achieve retribution. I am not arguing for a repeal of a defendant's Constitutional rights. I believe in these rights very firmly, including the Eight Amendment.
