A Daughter's Betrayal

When I read Nisus and Scylla, I couldn't stop thinking about betrayal. About the way some people betray their love ones for something or someone that doesn't really matters. I believe it is incredible how they make their love ones suffer just for them to obtain what they want. This people are egocentric and they do anything to obtain what they want, even if they have to sacrifice the people they love. And most of the times, they don't get what they want so the sacrifice they made was in vain. The people that suffered because of them suffered for nothing. Because at the end, those people didn't even obtained what they wanted.
In Nisus and Scylla, as I read, I was able to see this kind of betrayal. The King Minos of Crete, had made a war upon Megara were Nisus was the King, and Scylla was his daughter. But the war continued for a very long time because Megara couldn't be conquered as long a purple lock which was on King Nisus hair, remained on his head. But as the war continued, Scylla began to feel attracted and fell in love of King Minos. She wanted the war to stop and be conquered by him:
"Another woman, loving as I do, would remove with her own hands whatever stood in the way of her love. And can any other woman dare more than I? I would encounter fire and sword to gain my object; but here there is no need of fire and sword. I only need my father’s purple lock. More precious than gold to me, that will give me all I wish.”-Chapter 8, letter a.
When I read this passage I couldn't believe what I was reading. I couldn't believe that a daughter will betray her father that way. I thought to myself: How can Scylla do this to her father? How could she let the enemy conquer her city? Scylla was a perfect example on how someone could betray someone they loved for a person who doesn't care about them. Because when Menus found out what she did, he didn't want her:
"The gods destroy thee, infamous woman,” he exclaimed; “disgrace of our time! May neither earth nor sea yield thee a resting-place! Surely, my Crete, where Jove himself was cradled, shall not be polluted with such a monster!” -Chapter 8, letter a.
Scylla's betrayal was for nothing. Because even though she made her father suffer, she didn't obtain what she wanted. This myth represents how people can be selfish, and do things only for their benefit. Even if it means betraying someone they love.
