Overcoming evil with good can sound like Peter is telling us to ignore evil intent as though we are to do nothing to protect ourselves (1 Peter 3:9). That would be an unwise interpretation of scripture and would result in bringing more destruction both to you and the perpetrator. To avoid returning evil for evil we must ask ourselves what is the best thing for the one who wishes to harm us.
The very best for them is that they would stop doing evil, therefore it makes sense to do what we can to stop the evil actions. Sometimes that means reporting the perpetrator to law enforcement. It might mean turning them out of your home. It often means confronting them, but it never means doing them harm or rejoicing over evil that comes to them. Allowing them to suffer the consequences of their action is not harming them. It is allowing God to deal with them.
