Although RMAN can conduct all major backup and recovery operations using just the control file, note these advantages of using the catalog:

Some RMAN commands and operations function only with a catalog.
The recovery catalog retains historical backup information that can get overwritten in the control file.
The recovery catalog stores information about backups from different incarnations of the database.
