Unless you run it in check-only mode. I have seen systems blindly try to detect and *correct* problems in a filesystem cause tremendous harm. Even Windows prompts the user before taking such measures on removable media. The fact of the matter is you may have some unexpected situation that would be corrupted by that action. Maybe a newer version of the filesystem your version of fsck mistakens for corrupt. Maybe it had one type of partition table at some point now it has a new one you don't recognize, but you see a backup block and corrupt the storage by restoring backup block of what you do recognize.

The fact of the matter is, users should be asked/made to take corrective action in something like fixing a filesystem.
