Was Scylla the sea monster killed?

In Greek mythology, Scylla was not killed; instead, she was transformed into a monster as a result of a curse. She resided in a strait opposite Charybdis, posing a threat to sailors, including Odysseus, who had to navigate between them. Her fate remained sealed as a monster, and she continued to terrorize those who ventured too close to her lair. Thus, she lived on as a fearsome figure in the myths rather than meeting a definitive end.
