In a case of sending someone a computer virus, there's room to argue that it's indirect, that they damaged themselves by opening the file (albeit unintentionally), etc. What if I go over to your computer and actively crash it? Can I be held liable for damaging property that isn't physical?
I ask specifically about damage payments. Nezek is evaluated as the difference between the old value and the new value (Bava Kamma 8). But from an objective standpoint, there's no difference between the computer before and after. Although other payments may need to be made, does Nezek apply when the target isn't physical?
