Anger and Justice

Is it healthy to suppress anger, a natural emotion, in order to be non-violent in our communication? Is it wrong to condemn an act/ crime in strong words, especially if one is a victim? What would be your advice to a person who has been a victim of physical, social, emotional and psychological abuse/ crime- forget the incident and carry on with your life for there’s a lot life has to offer or fight the culprit legally and socially and bring him to book (because for a fight the person must preserve one’s anger otherwise the fight just fizzles out, going by how our police and the legal system work)?Wouldn’t the first option lead to more crimes, for I’ve rarely seen ‘Gandhigiri’ work?
