Forgiving people

Q: I keep hearing that we as Muslims have a duty to forgive others. But how can this be the case if we wish for them to be held accountable on the Day of Judgement?

I don’t want to forgive people who have hurt or harmed me as I want them to be brought to justice. And I don’t understand what is meant by ‘when we forgive it’s for us, not them,’ as forgiving those who have done me wrong does not bring me peace, but knowing they will be held to account does.
