This is the curse of an evil deed, that it incites and must bring forth more evil.
If you cannot please everyone with your deeds and your art, please a few. To please many is bad.
Song forbids victorious deeds to die.
There are evil spirits who suddenly fix their abode in man's unguarded breast, causing us to commit devilish deeds, and then, hurrying back to their native hell, leave behind the stings of remorse in the poisoned bosom.
