Answer
If handling it doesn't improve reliability.
Sometimes, catching an exception is unnecessary, especially if you can't recover from it or log it meaningfully. Allowing it to propagate can be better, letting a higher-level handler provide more context. For instance, if a low-level I/O operation fails, letting the exception bubble up can allow a higher-level handler to decide whether to retry or log the error.
