Why does Karl Moor surrender to the authorities at the end of The Robbers?

In Friedrich Schiller's play The Robbers, the protagonist Karl Moor surrenders to the authorities because he ultimately recognizes that violence, terrorism, and criminal behavior are not viable solutions to human injustice.12

Although Karl initially defies established authority as a reaction against corruption and the denial of justice, he eventually realizes that anarchy and crime cannot effectively reform society. By turning himself in, he submits to the law he previously flouted, allowing Schiller to frame the play as a defense of morality and the rule of law, even while portraying Karl as a "sublime criminal" driven to his actions by a corrupt society.12
