There's a distinction between "Corrupted seed" and corrupted PK / password. The seed is provided without validation or checksuming, generating perfectly valid keys on the fly from unknown entropy quality. If you have bad entropy (partially or fully corrupted/weak seed), you'll generate valid-looking keys that are actually insecure. There's a reason there's not a single "end-user" crypto-related app / cli tool or server that takes a user-specified arbitrary seed as input. That's dangerous, broken design. Why would you even do that?
