Question: the person accused of a crime is called the plaintiff

Answer: No, Most countries make a clear distinction between civil and criminal procedure. For example, a criminal court may force a convicted defendant to pay a fine as punishment for his crime, and the legal costs of both the prosecution and defence. But the victim of the crime generally pursues his claim for compensation in a civil, not a criminal, action. In France and England, however, a victim of a crime may incidentally be awarded compensation by a criminal court judge.
