Hmm... sleeping with Aigisthos while her husband Agamemnon was solving problems within the family. And then when he returns home she prepares a bath for him, casts a net over him and stabs him to death! I would not exactly call that a talent. A corrupted nature would be a more fitting term, I think.
But her vile deed would not go unpinished... Sofokles has written a great tragedy about that called "Elektra".
