1. If someone is a serial-killer, but they have since become paralyzed without chance of recovery, should you report? He cannot kill again…
2. If someone has stolen from a store, but their hands have since fallen off and he is unable to steal again, should you report him?
3. If a man is caught spying on people in the Mikva, but he has since gone blind, should you report him? He can no longer spy…
In all of these scenarios, there are victims, there are crimes, and there is a wrong-doer. In all these scenarios, the wrong-doer is now incapable of performing the wrong *again*.
